I think we got the bus from the Explorers about 9.20am. - Handy hint though - book the 8am breakfast at the latest & be there sharp the queues are huge for breakfast after then! We did that then went for the bus outside and that gave us plenty time to meander up Main St & get lots of photos before enjoying the rides etc..
Have a great time - stayed at the Explorers 2 weeks ago - really enjoyed it
