You need to decide first which tix you want. (snowgod is right.) Then check the sites. For instance, I DIDN'T want PLUS tickets since we'll only have 4 days (one per park) and no time for the extras. In addition, we're going in Dec., so water parks aren't as interesting to us. Here's what I found based on WHAT I WANTED:
(prices list 4Day PH adult (10 and up)/child (ages 3-9)
Disney Store 192/152
obviously no shipping and I'd pay higher sales tax here (6.5% in FL versus 8.25% here)
Disney web site 192/152
same price but I'd pay $3 shipping but FL sales tax I think.
paramountinternationaltravel.com only sold 5-day PHP
floridaorlandotickets.net 203/164
that includes tax, $7 shipping unless you want express
centralfloridatravel.com 202/162
that includes tax, shipping also $7
ticketmania 203/162
includes tax, shipping free right now...says limited time but I didn't see expiration.
So for us, ticketmania was the best total price, but I only saved about $9 over the Disney site. But hey, that's $9 more I'll have to spend on something else!
Many of these also will deliver the passes to your hotel/villa. Bottom line is that there aren't any deep discounts. You can join something like Connections or
AAA but I'd say only do it if you like the whole package--don't do it just to get the discount on entry tix since it doesn't really pay for itself. [This is also assuming you've checked special discounts you may get with your company, military discounts, FL resident or other such things.]
That's my research. Hope it helps.
