Most theme parks run their own specials, so before you visit, log on to the parks’ websites and click "specials" or "offers." You should always check the theme parks' websites first for any special offers to SeaWorld, Universal Orlando Resort and Walt Disney World Resorts. If you're an out-of-state visitor, check ticket brokers. Mousesavers offers various discounts throughout the year. AAA members can get discounts through AAAsouth.com. Another reliable source is the Official Ticket Center, which offers discount tickets for all the Orlando theme parks, plus dinner shows and other attractions. Also try UnderCover Tourist and Orlando Fun Tickets.
In the UK, one of the biggest ticket brokers is Attraction Tickets Direct and they offer the best deals available on theme park tickets. One of their best selling tickets is the Orlando Freedom Ticket, which provides 14 days entry to all the parks including SeaWorld, Walt Disney World, Busch Gardens, Aquatica and the Universal parks. Visit their website at www.attraction-tickets-direct.co.uk.
As a UK traveler it is advisable to book your theme park tickets before travelling to Orlando, they will be able to offer the best deals possible.
