Thanks for all the advice.

We ended up getting preferred annual passes. They were running a promotion if passes activated by April 30th: gave us Florida pricing and added three free months. Also includes free parking ($17 each time) as well as 10% discount on most food and merchandise purchases. Roughly $260 per pass. We came down earlier so using 5 days this week. And will "force" us to visit again at least once in 15 months! :-)

Seemed like a great deal.
