It is on your way back to the U.S. that you will have to pick up your bags in Dallas (or Houston). On your way there, they will check them through to Belize City, where you will claim them, go through customs, and then on to Maya (or Tropic) Air.
Ditto on the hairdryer/hairspray. Leave them home. Also, forget makeup... foundation just slips right off your face in the humidity, you definitely won't need blush
, and any eye makeup you usually use will soon be wiped away with perspiration.
I'm still working on the ideal Ambergris wardrobe. I know these things:
It must be 100% cotton (and lightweight)
Tops/dresses must not have any sleeves (even short)
Dresses should be free flowing, and have no waistband.
Nothing can fit tightly... air must circulate!
Restrictive undergarments must be avoided if at all possible.
My shorts are all "fitted", and I always end up wearing my hubby's shorts, which are about 2 sizes too big, but much more comfy and cooler.
And if you have long hair, be sure and bring something to get it up off of your neck (and out of your face in the breeze).
My suggestions... for what they're worth!
