We did a Mears shuttle from ASMo to Discovery Cove and I believe it was about 45 minutes-1 hour. We stopped at 2 other resorts (ASMu and ASSp) to pick up people and then stopped at Sea World before going to Discovery Cove. It was well worth the money ($48 round trip for 3 people). On the way back it took longer because we stopped at 5 or 6 resorts to drop off and we were the last to be dropped off, but it was nice to be able to see the other resorts, so we didn't mind.
