Notice, I'm not sure what you mean by chappy culture.
Just goes to show that you can't please all the people all of the time.
Whilst I was there last month, a 17 year old girl came to do her PPL and another was due in the day I left. They both stayed in the house. This was discussed before the girls got out there, if the girls had wanted anything else I am sure that it would have been organised.
To reiterate, Britannia treated me and everyone else whilst I was there as individuals. If you had any requests or special requirements they bent over backwards to accomodate you. It is a very people friendly place.
If you want to stay in different accomodation like motels or hotels you can. I didn't go out there to stay in luxurious accomodation, separate from everyone else, I went there to learn to fly.
The only thing to worry about is whether there are any social missfits in the house whilst you are there. Unfortunately, Britannia cannot guarantee this.
Just remember - There is a tw$t in every group, if you cannot spot him/her - it's you!
Best regards
