Hi all. We have a grand gathering booked for May 7-12, 2009. It is paid in full, booked thru a travel agent. We have a 6 day park hopper but we wanted a water parks and fun option. I did not notice this (my fault I know) We have our dining booked and don't need the hopper. Can we change our tickets at check in? I tried to do it through my Travel agent and she said it would be a $50 per person change fee plus a $50 upgrade fee I am hoping at the check in disney will just change them over...what is the chance of that? If they won't are there any discounts for a one day typhoon lagoon ticket? Thanks!
