We are very interested in the "Shipwreck Snorkeling Getaway"...it mentions the person should be able to climb a boat ladder. We are both avid scuba divers and have come across some horrible boat ladders that are extremely difficult to climb up, they are little more than tiny rungs. We are both 70 and have no difficulty with a ladder that actually has more than tiny rungs and handrails. Has anyone gone on this excursion that can enlighten me on how easy it is to get back onto the boat? Much appreciated !
