fitflops, or Birkenstock gizeh or Madrid. Although saying that each time I end up buying cheap flip flops from one of the Disney stores and wearing those for the whole time I'm there, then leave them in he bin as usually falling apart.
I've been lots of times now and the fitlfops or birkenstocks are the only ones I would contemplate taking with me. I find you don't dress up for the evening, just usually grab something on the way back from the parks before getting to the hotel. The first time I made the mistake of taking loads of maxi dresses, strappy sandals etc, now I take shorts, vest type tops, camis, etc with flips flops and maybe one outfit for smarter wear. Havent worn it yet.
There is lots of walking, think how big the parks are for a start, walking between each ride and land is a fair distance. The first time I went to florida as an adult, I was overweight and on slimming world, I did not stick to plan at all and spent the three weeks eating whatever I liked drinking full fat fizzy drinks. I came home lighter than I went, by over 7lb! I put that down to all the walking. as swimming was really just floating in the pool and lazy rivers so no exercise there.
We're off again last two weeks in august, can't wait. Saving my shopping money already.
