K.G.
we just got back-- we stayed at the NEW (marriott) Fairfield Inn and Suites just across the hwy. from Seaworld: ###-###-#### FREE shuttle to/from the park with cont. breakfast included used my AAA discount-- great deal!
went to www.seaworld.com for silver passport season pass (we may go back in the fall) just a few $s more for pass than the 2-day ticket and you also get great coupon books for food/games/gift shop 30% discounts and feeding animals.
We went to the riverwalk one day (stayed at the WESTIN for my husbands business part of the trip) very nice! the kiddos and I went on the river boat and to the IMAX (w/ 6 and 3 year old) at the RIVERCENTER mall go to sanatonio website for discounts too
Happy trip planning !
