I am planning a trip for myself and 4 girlfriends from the west coast. It seems as though the nicer restaurants are in East Hampton (where we're mostly likely to catch a glimpse of a celebrity) and the night spots are in Southampton. I am looking for a little sun/beach and shopping during the day with an option of dancing and more upscale dining in the evening. Where should I look to get the best of both worlds? We are only going to be there for 4 nights. (Thursday-Monday).
