Hi Frogga,
I live in a hot climate (in the summer) & I don't really notice anything that I can directly say is heat related. Of course I wear shorts & t-shirts.
It sounds like you will be wearing quite a bit more than that when you go out sight-seeing.
I'm wondering how the flight might affect you though. What about the pressurized plane? I've been thinking about this myself as I am still planning my trip to Hawaii (somewhere in the future) and it is a long flight. I've only been on planes for short flights since the RSD & that was before the leg swelling became such an issue.
I notice you had ALOT capitalized. Sounds to me like you kinda decided already. As long as you don't get ALOT more pain, why not?
sounds like fun. Hope everything works out.
