Tourney: Ladies Army IV + Coed Tournament - 27-29th April 2012

VWP is the Visa Waiver Program, which the UK is part of. ESTA is the Electronic System for Travel Authority.

Supposedly you need to apply for it at least 72 hours before check in now, otherwise they won't let you on board the plane.

The law changed last year (or year before?) to that ^ as I understand.

Well, i do remember around 09 they made you start "pre-registering" to see if you could enter the states, but i've only done that once.

I went to the states in September and still had to fill out a green slip to get my 90 day visa. I wouldn't worry about it.
