I am using some of MW points this Summer to give my parents and my sister a few nights away.

Couple of quick questions on this:
1) If I book the room in their name (rather than mine) will they still get Exec / Concierge lounge access and the possibility of an upgrade?
2) Am I better to book the room under my own name? We all share the same family name, but how tightly do they police this? One hotel would be in Europe and the other is the NY Marquis

Thanks all
