Just got back (April 8-15). Even though we had a double stroller we ended up carrying DS (15 mos) and DD (2 1/2 yrs) a lot. Not being in the best shape to begin with my lower back and legs got very sore. Then one evening we were sitting at Pleasure Island having a beer and I saw the One Minute Spa (probably not the right name) right across from us. I got a 10 minute aqua massage and no longer had a sore back. It made a huge difference in how we enjoyed the rest of our vacation.
