Disneekrazee- I will add to kristlews comments about the transfer day assistance, that with ABD there were multiple benefits while on board the ship that even the other groups on board didn't get (We had a Japanese tour group and a British group on a 6 week long grand tour of SA) Check out my review where I enumerate them all in a "tips" section, all kinds of things like first seating for meals and getting out first for excursions etc etc. As for pricing differences, they are largely due to popularity, ( for instance holiday periods are always more) but also, the trips are priced with some early booking slots at one price and then once those are gone, the next slots are X+ and then once those are gone, the next folks to book pay a little more. Say hello can probably explain it better than I am! Kristalew- I love the refugee comment...I know I was wrung out and cranky, I can't imagine what it would have been like without the VIP lounge and someone holding my tickets and moving my luggage and getting us in the right lines!! The line to board the zodiacs to get on board the GE2 was the worst time, the other pax were pushing and shoving...I was glad I had my ABD guides to tell us what was happening!!
