The Navigator reminds me of an aging movie star - still very lovely, but showing her age in places and finding it very difficult to compete with some of the younger offerings despite extensive cosmetic refurbishment.
We were a group of 10 ranging in age from 59-72, and all have cruised before. We generally cruise with Oceania. Our satisfaction with Oceania's offerings factored in our decision to book with Regent, which was described as the next level up in the NCL firmament. The main consideration was the African itinerary - voyaging from Cape Town to Cape Town over 15 days.
A 3 day safari was offered as a 'booking bonus,' and that part of our trip exceeded all expectations. We stayed at the magical Eagles Crag Lodge in the Shamwari Game Reserve, and would rate that experience as flawless.
We were midship on the 5th floor. Cabin was excellent - lots of room for storage, more than adequate bathroom, very good and extremely unobtrusive cleaning service.
St. Lucia Wetlands- Big bus to the dock for the wetlands cruise. Cruise for 2 hours or so, with many hippo sightings (of course all lazing in the water as it's daylight) a croc or two, many small birds and an eagle. Good hippo sightings, but underwhelming because of the 'disneyland' feel.
