I think I'll do the half-half thing; brief overview now but just ask when I get there. Heh, I'm a huge planning freak, so I like the idea of getting a basic idea first.
Does cheap and decent in SD = taco stand/fast food? With all the fun attractions and such I'm already up to $60/day , so I probably will have to do cheap and decent.
I hadn't thought about cooking in the hostel. Do they already have pans/pots there? It sounds like it would be a fun adventure of its own. Thanks for the advice, Omisan!
