Hi, I've just booked our first non-Disney Orlanda trip for August. I'm very interested in hearing experiences, tips, do & dont's for Discovery Cove. We're also planning on visiting Sea World - have never been there. My 9 year old son loves animals - not so hot on big coasters - we're staying at Hard Rock. Any suggestions on best passes (most economical) for Sea World, Discovery Cove, IOA and Universal would be appreciated. Thanks!
