We chose this cruise for several reasons: 1. we hadn't been on Regent for over four years and felt it was time to give them another try; 2. we wanted to see the Panama canal; 3. it was an expensive way to get to South America to visit our friends in Ecuador.
We are Gold on Regent, and this was our 12th cruise with them; we go back to 2000 on the Paul Gauguin. We had sailed on that ship, plus the Diamond, Navigator and Voyager but never Mariner. This was also the longest cruise we had done, 18 days.
We had an H GTY, which meant we didn't get a cabin assignment until a few days before the cruise. We ended up in 829, which is an accessible cabin. I liked it, and would book it again. It was quite square in shape, and had no walk-in closet, which made it feel very roomy, roomier than the standard cabin I think, and still lots of storage space. Only downside is the bathroom shower--no enclosure to allow a wheelchair to wheel in, no cabins below the sink for the same reason--showers entailed laying out towels on the floor around the shower to prevent daily floods. They do need to replace the safes, but I believe they will be during the next refurb.
Good embarkation. Easy taxi ride from the Holiday Inn.
Visited a church which was a miniature version of Sacre Coeur in Paris. Spent a couple of hours at the Balata Gardens--beautiful.
