No,there are not.
Welcome back A of N (you should have rung Sukie though, it was great)
From the Royal Caribbean website:
Every night is an exciting night onboard a Royal Caribbean cruise, but we're not afraid to add a little flavour - just for good measure! Hide your true identity at our Masquerade Ball or do like the Romans did at our Toga Party. Or be a part of our mystery theater over a delicious Italian dinner - be the first to crack the case! Themes vary from ship to ship, so you never know what you're going to get. We like that element of surprise.
Theme nights include*:
Rock 'n' Roll Night; Masquerade Ball; Toga Party; '70s Night '80s Night; Big Band Night; Kids' Pirate Theme Night and Mystery Dinner Theater - a unique event at Portofino
These will not be in the main dining area but other parts of the ship.
