Although I am not as experienced an outdoorsperson as some 'round here, I like to have a bit of room in my tent. Bivy sacks and solo tents are too cramped for my tastes, as I like to keep my bags inside the tent.

I've used a Kelty Teton 2 and am pretty happy so far. Good price, well made, and only weighs 1 - 2 lbs more than most solo or ultralight tents.

AFAIK it will be pretty humid there, so you might want to make sure whatever tent you use has plenty of ventilation.
