I signed up for it... everything was arranged, I received the booklet, t-shirt, package etc. I phone them the night before to ask where to meet the rep at the airport was told that they didn't receive my final deposit (due over 6 weeks ago) and had assumed I didn't want to go anymore. We did send it so it must have gotten lost in the mail but we still kept receiving information, itineraries etc from them so we had no idea they didn't receive it. We were out about $500 from ticket refunds and the non refundable deposit.
Anyways so that's my rant.
As far as the program goes - it looked really interesting. My other friends that went had mixed opinions. Two really enjoyed it and the third hated it.
Cheers,
