It's VERY easy to get to Universal and/or SeaWorld from Cypress Pointe; you don't even have to get on the interstate! If you're at Cypress Pointe*, make a left out of the entrance, go to the end of the street and make a right (I can't remember the name of that street) follow to the stop sign and make a left on to Palm Parkway. Just follow Palm Parkway (it will change names to Turkey Lake Road) all the way up and Universal Studios will be on your right.
Sea World is even closer. Follow Palm Parkway to Central Florida Parkway and make a right. Go straight on CFP and Sea World will be on your left, Discovery Cove on your right.
*If you're at Cypress Pointe Grand Villas make a right out of the entrance.
Your trip should be less than 15 minutes to either Universal or Sea World.
Have a great trip!
