I was just reading a post by Jesse responding to the residency requirements for AC and he mentioned:

".... If you simply come here and stay, renewing your tourist visa every 30 days ......"

We have our first trip booked to AC for early December and I haven't done a thing about getting a visa - is this necessary for a 9 day holiday (2 coming from US, one w/US passport, one w/UK passport)?

As I've booked the trip myself w/o travel agent I hadn't thought about visas, only any medical requirements.

Could someone point me in the right direction linkwise or let me know on the board here if we should also be obtaining visitors' visas?
