First Universal/DC/ seaworld/ trip have always done just Disney. Loving how we don't have to book every single moment of our trip except for our Discovery Cove day! We really want to dine with Shamu but not sure which day of our trip will want to do SeaWorld if I wait until we get there will it ruin any chances of getting a reservation or should I just bite the bullet and book and plan that as our SeaWorld day? If it help we will be there 8/20- 8/27
