We just came off the Pearl back in June and had great concierge service with added/changing dining reservations. The problem we did have was the concierge cancelled dining reservations twice on us. I think he had us confused with other guests. Thank God for the app. After it happened the first time, as we were checking in... and we were told our reservation had been cancelled by your concierge two days ago... I started checking and it happened again - but I caught the second time early. We were turned away the first time it happened, we were not pleased!
So, keep an eye on your future reservations!
