What about someplace in Mexico that you can access via SFO or ATL? Like San Miguel de Allende More links (fly into BJX-then taxi or shuttle). Or into mexico city and buy a ticket someplace, I think you can get reasonable priced tickets ($50-$100) to other areas of Mexico. Or for the west coast person fly down to LAX then a lot more options of airports that LAX and ATL service, like Costa Rica and El Salvador. that would just save some time flying across the U.S. to meet up.
