We love the club at Portofino. The room is quite large and we have never had a problem getting a table for our party of 5 (sometimes 8).
There are 5 different food offerings, starting with a continental breakfast in the morning, usually a fruit cup offering in the mid morning, gelato in the early afternoon, appetizers with beer and wine in the late afternoon/early evening and then dessert in the late evening.
There is no separate club floor, so some of the rooms can be quite a hike. While the standard club rooms are deluxes, anybody can add club privileges to any room for approximately another $75.00 a night. This can be done at check-in if there is space available.
There are some pictures in the Portofino sticky at the top of the page of the breakfast set up with a description of the foods offered. I will try to dig them up and post them again.
If you have any questions, just ask
