I’ll be in MB this Saturday (20 June) until the 27th. I’ve seen the websites for both of those places. Murrell’s Inlet is probably closer to our condo (Compass Cove). My 9 year old wants to do a "Discover Scuba" and I’m going to try and get at least one charter in for me during the week. I’ll look harder at Express.. I know they do the Discover.. Thanks for comment..
