Beds

 Having spent way too long looking at different types of accommodation both within and outside of Disney World, something has begun to bother me.  Why is everyone staying in a Disney hotel expected to stay in the same room with multiple beds?  We're talking some rooms big enough to sleep up to eight people, but all within the same living space, not separate rooms. 

Is it just me as a Brit who doesn't want to share a room with even my own children or close family?  I find it odd to say the least, especially when you're just travelling with adults, as is often the case.  

Are there not others who get up / retire at different times?  For example, Phil and I are classic early-to-bed-early-to-rise people.  We will be travelling with Lyta and her fiance who prefer to stay up later and get up at a more reasonable time. So while we want to go to sleep, they'll be still up watching TV; but in the morning when they're still sleeping, Phil and I will want to be up and making coffee, and planning the day.

We have pretty much given up on finding a Disney hotel we can afford, since we need two rooms; and have decided to spend considerably less on renting a whole house through AirBnB.  It does seem a shame; but we cannot think of a better way to get our own space. 

I'd be interested to know what others, especially native US guys, think the same way.
