Where should we go this spring break?

Our plans fell thru... Scrambling for a fun trip with two kids, age 5 & 7 for a week during spring break. Open to anything except Europe as making that trip later this year... Someplace warm would be good... Either Florida, Cali, myrtle beach? mexico? Something beachy yet has other activities... Anything come immediately to mind? Loved beaches Turks and Caicos with kids, but way too expensive this late in the game. Never been to the keys- wondering if anything besides the beach for kids? Trying to find last minute trips online, but I always need to input a destination, and I am pretty open on that end. Any suggestions ?

we were just in Puerto Rico last month...Ritz Carlton had a lot of families. Probably other places there even more family oriented. Easy flight, hotels very close to the airport but not in the flight path, US currency.

ooh - yes, a cousin went recently, and stayed there too! She really liked it there with her family, and I think she used points... Will check this out. Thanks!
