We have a 32 FT Class C which sleeps 7 has one slide out. At Disney we have had up to 8 people, sleeping in our RV. The back bedroom has a queen size bed which my daughter, granddaughter who is now 8 years old and I sleep on. The table is the horse U shape so it's about a full size bed but a little bit longer. We had one tall adult (six ft) with his child (8 year old) sleep there. In fact my husband and I, both slept on the table before. The couch is small and I would say two children would be just fine on it. I've slept on the couch with my granddaughter when she was 5 years old. The couch was really soft. My husband loves to sleep on the couch without even making it into a bed. Now to me the over the cab bed is larger and longer than the queen bed or at least seems as wide as the queen size bed but longer. My Grandson who is 18 years old and his friend same age has slept on it. So the RV can sleep 7 or 8 depends on children or adults. I love my RV if I could change anything it would be, that I wished I had known about the super class C, as it can carry more weight. We usually bring a car, if my husband is coming down to Disney with us. We always have tag along with us. If you say you're going to Disney you will get tag along. I think it okay at Disney to have 7 or 8 people, as you spend more of your time at the parks, so you not on top of each other. We also love being outside most of the day, so we are using the RV mostly to sleep in or watch TV. We even cook outside all the time. I've never used my stove inside the RV. You have three small children, so you would be find with having your parent go with you and your small family. If you decide that you may like having an RV, I would go look at them and try them out. Make sure you try out the toilet to make sure they are tall enough from the floor, as some are small and you want to be comfortable. Try out the shower to make sure you have enough room to take a shower, as some are small. I would laid in all the beds, by making up the table, couch and over head cab. Some of the beds may need a form topper. As far as driving the class C, I love it and didn't think I would ever drive the RV, but it's like driving a truck. I for one was afraid to drive even a truck, but I don't mind driving my Class C. I rather drive the RV than my mini van. So if I can drive a class C anyone can. My husband took me out driving it for one day, and since then I drive everywhere. Now Winnebago didn't have a rail to lock the children in place, in the overhead cab but the Coachman does. Now that my granddaughter is 8 years old, she wants to sleep in the overhead cab, so this last trip I brought a rail for bed and we hooked that up and it does keep her safe in the bed. Honestly I think once you get out looking and see what you like, you will know if this is for you. If you like camping in a tent, you will totally enjoy it in the Class C. I don't even want to drive a three hour drive in my mini van, as I would rather take the RV.. lol..
