I usually say "Florida." When pressed I say "Disney" If I get the "again!" thing, I usually get off on a tangent about airfares-- the NYC-Florida market is really competitive these days, and I tell them with airfares as cheap as they've been the last couple years, it's crazy NOT to go.
Which is complete horse manure of course, sure we all love the $105 round trip tix, but the savings are a drop in a bucket compared to the total cost of on-site accomodations, theme park tickets, that food, the STUFF.... but I convince them we're doing it for the bargain. Everyone can appreciate taking advantage of a bargain.
