I never really experienced the mosquitos either and I tend to attract them for some odd reason. I'm just that sweet, I guess.

Yes drink tons (more water than alcohol though)! Which leads to taking your time, don't rush. If you want to rest, then sit and rest.

Don't let the rain scare you away, the parks and alike clear out when it rains. I think a lot of people believe they will melt. I think a small travel umbrella works out nicer than the poncho. Those are cheap at lots of places.

The rain storms are pretty normal and tend to be like clock work. And in reality, when it doesn't rain it's even more hot.
