We loved it. The only concierge level perk that we didn’t experience was a private character meet and greet, which was to be expected.
They did add a few new perks. There was a bar tender up on the sun deck for extended hours and there was an elevated drink of the day cart that goes to the concierge stateroom. We were on the Dream and experienced a spritz cart, an old fashioned cart, a martini cart, and a Moscow mule cart. It was so much fun scheduling the cart to come to your room and waiting for the doorbell before dinner.
I’d recommend concierge now.
