Hey. I'm off to WDW 6-14 March next year to do the princess half marathon with Mum and Dad (they're early 50s as a hint!). They're staying another week when i come home and are looking for somewhere to go that's not too far away and maybe a bit more relaxed. Will it be too cold for a beach resort in mid march? They've been to clearwater and sarasota and enjoyed both so they have potential.

Thanks so much
