Definitely a bargain for a YC deluxe suite. On top of what others have mentioned, you also get a dedicated check in area and priority boarding and disembarking, which is a huge plus when the ship is full.
We have been in the Mera three times, all in YC, the rest of the ship tends to be very crowded and it is great to be able to retreat to the sanctuary of the YC Top sail lounge or pool deck and escape from the craziness of the rest of the ship.
