Where do your guests sleep if you don't have a guest room?

No.

No one who *lives* here gets kicked out of their room that *belongs* to them for the sake of someone who is looking for a place to stay for free.

Funny... We were juggling rooms tonite for my parents to spend tonite with us.

4 bedroom house...
Master bedroom- king bed- DH and I
DD's room- queen size bed, she will be giving up her bed tonight for nana and papa to sleep in there and she will sleep in our bed with us. She's 4.
Bedroom #3 is in the process of being painted and done for our little boy who is due in March, There Is a taken apart full size bed in there along with TONS of misc. stuff that we are organizing,
Office/craft explosion room/music recording room/floor plan plotter room- this is DH and my space. It's a mess. Eventually, it will be organized and cleaned up enough that we can put an air mattress in the middle of the floor.

We also have 2 8 foot couches people can sleep on. and 2 lazy boy recliners that are super comfy to crash in.

If push comes to shove, we can put air mattresses in the living room, push the couches together, put an air mattress in the dining/play room and move out the table. Not a big deal. We're flexible.

In the future, the kids will either sleep in with us or share a bed or sleep in the living room. No biggie. We don't have company THAT often that stay over. There are NO hotels in my town and the closest is over 30 minutes away! People are always welcome to crash here. We just get creative with sleeping spaces.

My husband and I will always use any extra rooms for hobbies/offices, something that we could use all year as opposed to a guest room that wouldn't be used very often.  We also have a lot of "stuff" (I live with 4 packrats! ) so we need a place to put it!

When we bought our first house, in another state, it was just my husband and I and our house was 3 bedrooms.  Master bedroom, study and an extra bedroom, very small.  We were going to get a double bed to put in to use as a guest room.  My mil told us we needed to buy a queen bed for that room because it would be more comfortable for her.  Well, I wasn't going to do that because I didn't want the room to be all bed and I wasn't paying for a queen bed when we already had a double.  But then I got pregnant, so it was going to be the baby's room, so didn't have to worry about the guest bed at all!

Have the room but do not ever invite overnight guests. I have a bed in one of the bedrooms on the first floor, but it is in case one of us is sick or injured and can't make it upstairs to the master bedroom.

Just the thought of company from the time you go to bed then from the moment you wake up to me is not a pleasant prospect.

OMG yes! I not only had to keep my room clean but my toys were stored in the basement , plus I had to out of my room when a bride was getting her portrait done.

My brother never had anybody in his room and got to keep his toys in there.

I slept on the floor in father's office, because the adults were in the living room. Sometimes my aunt would come get me.

Thankfully our house has three levels, so you can hide a kid somewhere or double the kids.  

I have a 2 bedroom 1 and 1/2 bath townhouse. I'm a more the merrier type. When the Oregon Ducks were in the Rose Bowl in January, I had about 10 extra people staying with me that traveled down from OR. There were people crammed everywhere, but we had a great time. I'm kind of surprised how many people are anti-guests at their home.

In my experience, if someone is coming to spend time with you, they really don't care where they sleep so much.   Our home is tiny and when relatives come to visit, they get the couch or an air mattress in the family room.  With FIL and MIL (before she passed) visted, they took our room and we used the air mattress.

Now that's it's just FIL to visit, he happily sleeps on the couch.

I can't get past the fact that you have a five bed roomed house, can't make room for your sister, and are surprised that she is aghast.

We joke we don't have a guest room so people don't stay too long! Lol 

Just kidding. Kinda sorta. 

No really we don't have a guest room. We have a media/playroom/guest room with a futon in it but not all guest fit on it if they are over about 5'8. So we put them in my sons room on his queen size bed. We would give up our room if need (king size bed) if needed but no one ever wants to do take that but we would be fine with it. Our futon is really very comfortable. I slept on it for 2 months when our youngest was born and that room was his bedroom. 

If we had a house with enough rooms I wouldn't mind having one but we don't. It would be nice but I don't place it as a priority. My dh's parents come 1-2 times a year but never for more than a couple nights as they have other family members to visit so they skip around. My mom is local and my dad has back, health issues and can't sleep in a bed so he sleeps in a chair. 

Are we talking people who you invite to come visit, or those who just pop in on you?

The issue for me, based on the original post only, is that sister evidently had issues staying with HER Mom, who had not one, but two guest rooms ready and available for her.
The guest rooms were not across the state, but across the neighborhood.

OP I agree completely with your decision, and feel like sister is the entitled one, expecting you to prepare a room and spend money you obviously weren't ready to spend, in setting up a guest room for her, when she could have easily stayed with Mom.

This from the person who is madly getting the previously ds vacated bedroom (he took his furniture) set up to host five guests, three adults and two teens, who are coming from California Thursday for ten days for the deer hunt and Thanksgiving.... But they are all guys and are happy as long as they have a place to land, be it guest room, air bed, couch or camp cot!
