With my family, not only would I want separate rooms, I would also want to be at separate resorts! Too many different interests, even pace of walking would get annoying. However, we could meet for lunch or dinner and then go back to our own humble abode. Yes, it would be more expensive, but with my family, it would be a much more enjoyable trip. Same goes for traveling with friends -- nothing like not being in each others' face 24/7 -- otherwise it isn't a vacation - -it's a prison sentence. God, I sound like a horrible human being -- just one man's opinion.
