Hello there! Am finding it very difficult to find something so any help would be appreciated.

Am looking for a destination (Mexico or South America) which are accessible via nonstop flights from both SFO and NYC (any airport). This is for two sets of families that are looking to go away during Thanksgiving.

Cabo seems to be the only option I can come up with, but they are looking for 2 more options from me and I'm totally stumped. Mexico City doesn't have a beach, so that's out.

Help?
