I would like to purchase 4 tickets for DC with dolphin swims. We are planning to go in Oct and would like to also do 1 day at SW and 1 at Aquatica. I was planning to order tickets through Undercover Tourist. Is there any disadvantage to ordering through UC vs. the DC web site? Would there be any benefit to waiting to see if there are any deals, or am I just better off ordering now when there is availability? Thanks in advance.
