We are just off this cruise and it was fantastic! Responding to the question about mobility issues, my husband received lots of help getting on and off the zodiacs and in the dinning room, one waiter immediately appeared at his side when there was a buffet. He did get off the ship for some of the zodiacs wet landings and a there was always help to get off the zodiac. On several occasions the very nice young ship's doctor was helping the expedition team at the landing sites.
