How long should we allocate for each park? We have a flex pass giving us admission to Universal, IOA, Sea World, Aquatica and Wet and Wild. We have four days. Can we do Sea World and Aquatica in the same day? We are not really big on shows so would probably do just one. We have a 17 year old and 11 year old. If we had to choose between water parks should we do Sea World or Aquatica? Is it necessary to get there at opening like at WDW? We are staying at Universal resort.
