for two reasons which you must evaluate their relevance to you.
1) Depending on the relationship of ALL individuals among each other, staying in the same place, eating at the same time?, implied group-only activities, etc. A vacation can become less than enjoyable, so certain discussions need to happen before departure, including a) group-meals or each his own and when, b) any baby-sitting expected/needed, c) any nights out and d)regardless of accomodations I recommend you decide who wants to do what/when and only try to involve each in the activities that interest them rather than trudging along with the group knowing they could be somewhere else doing something they want to do. Everyone is on vacation and expects to have fun. Group-think can spoil a vacation.
2) The BWV is ideally located to allow very short hops to two very fun parks (for both adults and children), and the boardwalk/. Given my comments above, getting out for quick one or two hours jaunts (essentially nap length) can make for big attitude adjustments if needed. Not having to worry about buses, etc can make a huge difference, especially if the parties may want to split up in the middle of MGM or EPCOT. We are a family with three young children, and my wife and I have occassionally split up, one with the stroller, one without. Either of us can get all the way back to the room without ever having to take the twins out of the stroller (you cannot do this with a bus).
Anyway, that's my two cents.
