We will be on the Eclipse to Alaska in August and originally booked an aft corner SI Sky Suite which we have enjoyed several times on Solstice class ships.
With a recent price drop we talked to our TA and she was able to get us into a Celebrity Suite on the hump for next to nothing more. We decided to do this because once you are fully paid up, as we were, you can only work a deal up class. While we will miss the view from the aft S1corner suite, we will appreciate the shorter walk to our suite from the elevators! Oh and we got an additional OBD for the upgrade plus more CC points per night as if we will ever see Zenith.
Our last trip on the Eclipse was to Hawaii and we splurged on a Royal Suite which was quite something.
Nevertheless, we always try to get an aft corner S1 when we can but in this case we will try a Celebrity Suite.
