I have two cottages at the Cottages at Camp Creek. We LOVE it there, as do our guests. It's a quiet community of about 20 something one-story 3-bedroom/2 bath cottages and 6 3-story cottages in front and in back. Many of the cottages have large porches (large enough to be considered outdoor rooms), and the pool is very large for the relatively small number of cottages. One of the things I like about the community is that the one story cottages give you a real sense of space. When you look up at the sky from the pool, you see a lot of sky (and stars at night) rather than tall buildings. We float in the pool at night and look at the stars.
The community is across the street from a lovely uncrowded beach. We like the east end of 30A because it has Rosemary Beach just a bit over a mile from us, the Villages of South Walton (with a great fountain that dances to music around 8:30 each night and kids run through it -- awesome), Fonville Press at Alys Beach, 1 mile from Deer lake state park (awesome), 4 miles from Seagrove, 6 miles from Seaside, 10 miles from Grayton beach. We are 4 miles from a Publix to the East and about 4.5 miles to a Publix from the West.
But, our guests (and we) pretty much spend our time in the summer there at the pool, at the beach, and on the porch.
That said, I would be happy with either Old Florida Cottages or Cottages at Camp Creek (I would have happily bought a place at Old Florida Cottages but we happened to choose Cottages at Camp Creek). They are both wonderufl places. I think your choice will have more to do with the layout of the places you're considering renting and whether you want to be on the west end (nearer Destin) or the East end (nearer Panama City). And what you want near you if you do venture out during the days. We are very happy going to Fonville Press for coffee (and the Friday after beach get-togethers), the fountains, the beach, Deer Lake State Park, and wandering around Rosemary Beach -- all within a mile or so from us. We were there in July last year, and I must say for all people say about how busy it is in the summer in SoWal, we were surprised at how unbusy it felt when we were there -- the beach wasn't crowded, the roads weren't crowded, the bike path wasn't crowded. I truly was surprised.
The biggest difference I can think of is that the Seacrest Beach area has dunes and the west end I think is flatter.
I'll pm you more information about the Cottages at Camp Creek. But I really think you'd be happy at either place -- do one area this year and then another one next year so you can compare for yourself. All the beaches are lovely. (Again, our beach is uncrowded where we are; I don't know about the beaches near Old Florida Cottages --someone else would know, though).
