Yes, we have done the "commute" over from Great Harbour more than once. We just head directly to the beach at Deadman's when we do since unless you are in a slip or on a mooring ball in Sprat, you are not welcome at the pool or in the marina showers, etc. Easier to anchor in Deadman's but Great Harbour works just fine. I am sure you could still make an appointment at the spa - I've heard varying reports as to whether or not the treatments are worth the cost.
