I've had AP's for the Sea World/Busch parks for about 10 years now,my first year I had a silver pass for only Sea World Orlando and Busch Gardens Tampa.On my second year with the pass I went to visit Busch Gardens in Virginia,I upgraded my pass to the Platinum to include all 8 parks at the time.I did the upgrade at Sea World Orlando as we left on the road trip.I've always paid it on EZ Pay so the upgrade was just going from paying $11.52/mo to $12/mo and doing this now gets me into Busch in Virginia,the waterpark in Virginia and Tampa and all the other parks in the chain,definitely a good deal.To this day I'm still only paying the $12/mo since I've never stopped paying it and they don't raise the payment as long as you're paying it,I think right now the Platinum is like $18 or more a month.The only drawback is that when they opened Aquatica they wanted me to upgrade my pass and go from $12 to about $17 to include Aquatica,if I was closer to Orlando and could go more frequently I would have considered it more but for once or twice a year I decided to keep my payment at $12 and just pay the daily admission when I go.However having seen that the Platinum passes are cheaper in the outside Florida parks when I go visit Busch in Virginia or Sea World in Texas I might just cancel my pass and get the platinum pass in one if those parks which will then include Aquatica.
