ok, so i'm going to Orlando for about 5 days in December and have two days to kill and want to go to either universal studios and islands of adventure or sea world and bush gardens, i have been and went to all the parks in 1999 except for ioa. i haven't rode sheikra, kraken, hulk, or dueling dragons and i want to ride them. online it looks like i can get two days at either the universal parks or bush parks for around $80...so my question is which two parks are the best to go to if i only have time for two??? also is kraken and shekira better than hulk and dueling dragons?
