I've booked a fairly last minutes Florida trip for September. Staying at Universal, will do their parks and some of the Seaworld ones. No plans for Disney in a 7-night trip.
Its interesting to look at the prices at the moment for tickets from the UK.
Universal is £301 for 14 days, 3 parks with park-to-park access. A bit pricey as will probably only do each park once, but OK.
Seaworld is more complicated.
Discovery Cove (without Dolphins) is £180 including SeaWorld and Aquatica or £199 with Busch too. Includes free parking at all parks too
or Seaworld, Busch, Aquatica for 14 days (with parking) is £153
or One visit (so three days total) to each of Seaworld, Busch, Aquatica with all-day-dining included is £141 (but need to pay parking).
They really do seem to be pushing the all-day dining. But £141 for three theme/water park days with food feels like a great deal compared to Universal!
(Disney is £480 for 14 days, but that gets you six parks and photos included).
Food prices at the Florida parks do seem to be a bit crazy at the moment, most burger and fries is now $15+ and with the drop of the pound/dollar rate it looks even worse to us. The way Seaworld are doing it seems even crazier, just put the price up by 5% rather than a weird surchage.
