Yes, you can purchase the 1 day base tickets and then upgrade each ticket individually. Personally, I'd buy for everyone the cheapest ticket wanted. For example, if the cheapest ticket is the 7 day base, order everyone that (at the cost of a 4 day ticket--not much savings, but every dollar helps) and then do the upgrades from there.
Thanks! I assume that once you use the 4-day base ticket it will apply an upgrade value of a 7-day base ticket? I think I need to get everyone the 7-day base tickets even though we really want hoppers because a 7-day hopper is MORE than my dad's florida resident season pass would be. But because the hopper add-on is a flat rate $50 I don't think there's a disadvantage to doing it this way. Am I missing anything?
Thanks again - jackie
