Universal are currently doing a 2-day 2-park pass offer with 3 extra days free. They do have to be used consecutively but still work out a good deal at $99.99 + tax. If you go to
www.universalorlando.com you can look at the various ticket offers.
If you want to visit Sea World as well, depending on how many days you want to visit you
might be better off buying a 4-park flex ticket. From memory, I think
www.attractionticketsdirect.co.uk do these for about £110.
Alternatively, they sell Sea World passes on their own for about £35 - and, again, I think there is currently an offer where you can return any time within 7 days as many times as you want by upgrading the tickets free at Guest Services.
For Disney World tickets, you have various options. If you are only there 10 days and you want to do Sea World and Universal/IOA as well, that means you probably won't want any more than 7 days maximum for Disney. You can buy a 7-day Ultimate ticket, which gives you access to the water parks etc. as well but, personally, I think these wouldn't be economical as you only have 10 days in total anyway. An alternative would be to check out the prices for the Magic Your Way (MYW) tickets. There are various options that you can add on, such as 'plus' visits, hopping privileges and non-expiry (which could be useful if you intend to go back in the future).
We usually find that, during a 14-day holiday, we don't go to Disney any more than about 6 or 7 days.
If you register at
www.mousesavers.com to receive the monthly newsletter, they quite often have discounts on MYW tickets from
www.ticketmania.com or
www.undercovertourist.com
We used
Undercover Tourist last year and were really pleased with the service.
Hope this helps
