Waah for swollen ankles! The humidity won't help. Drink a lot of plain water, keep your feet up the rest of the night, and if you have access to a water pill and a banana, take them in that order. If not, try to down some ibuprofen before you go to bed to help with the swelling. And if you have a single aspirin (real aspirin) take one. Watch your salt, too. *hugs* I'm so happy for you and Pi -- you're going to have a supertastic time! :-D
