I see that Discovery Cove currently opens at 7AM. Our trip to DC is Feb. 2022. Will they still open that early? Also, when are the dolphin swim times throughout the day? Finally, we are staying at SSR. Should we book the Mears roundtrip shuttle instead of Uber because I have seen that Uber is hard to come by and expensive with the gas prices. If we take the shuttle, will we be with other people? Also, the shuttle's earliest pick up time is 7:50 AM. Is that a problem in terms of our day at DC? Thank you.
