Thanks GTBM and CCK: Perhaps we'll try it out in June or August when we're there as a family. Sounds like a great place to know about. I was more concerned about the drive to get there in the summer, but maybe it's not as bad as I thought! If it rains when I'm in SoWal in May, I think I'll just sit on the porch listen to the raindrops on the tin roof.
Cork: I certainly understand. It's somewhat the same when you own a vacation place and rent it out. Whenever I go there, I always have a lot to do to keep the cottages in shape (I'm a do-it-yourself-if possible-person) -- maintenance, cleaning, cutting down native thorny vines in the native landscape (those vines are the only annoyance of the native landscape -- everything else about it is wonderful), buying stuff for the cottages, bleaching the white wood on the porch to get rid of the mold at least twice a year, etc. But even with all that, it's great to be there. And I think some of the work is of my own making -- I'm going to try to make myself do less when I'm there and relax even more. But even when I'm working there, the beach/weather/space makes it a wonderful place to be.
