I agree with Marc and have some additional comments. Before the ship was launched Regent touted smaller suites for singles but don't list that they will also place couples in them. We're used to booking the low category price wise and got G-2, the single suite. The suite size we got accustomed to, but the 2 - 3 foot wide clothes hanging rod is ridiculous. The room is very narrow with a wall segment protruding from each side making the bedroom quite dark and the TV is on the bedroom wall and very difficult to watch from the sitting room.
The seating in the theater is very packed and difficult to navigate between the rows to get a seat in the center of the row. It's also a very tight squeeze for servers bringing drinks & canapes to those seated away from the aisle.
There is no Horizon or Galileo's lounge at the rear looking out over the stern, Instead there is a Meridian Lounge mid ship on deck 5 and, even though it has side windows, it can be dark..Observation Lounge is the only place to enjoy drinks with a view.
The staff has been great as always and, even though we're enjoying Frolic, the Explorer is our 4th favorite out of 4 ships in the fleet and she's also the most expensive. We've really enjoyed the Navigator since her refurbishment, the per diem is about 1/2 the other ships, the new itineraries are very interesting with sea days rather than port intensive and my response to old complaints is "What vibration."
