We also used this tour provider for our cruise on the Apex in October. They guides are fantastic and very knowledgeable. Each day was 10 to 12 hours due to the distance and traffic.
We asked for the recipe in the Retreat and the bartender said everyone does it a little differently. If you look at the drink menu for the Retreat it has the ingredients.
On more than one occasion they lost our food orders. The last time we just got up and left. We did tell the manager on duty about the issues. They sent a bottle of wine and asked us to come back. We didn't since the MDR was better.
We are sailing in September and I asked my travel agent if the retreat updates would be done by then. She called Celebrity and they told her that the ship would be revolutionized in May 2023.
We are currently on the Apex with 2000 guests and not all the stations in the OV Cafe are open. This is due to staff shortages and not being at capacity.
