Hawaii Celebrity Summit cruise...are there formal nights?

Just wondering if Celebrity has formal nights on its Hawaii cruises?

Specifics: Summit 14-night R/T LA to Hawaii on December 8, 2006.

Thanks.

On a 14 day cruise to Hawaii on Summit you will likely have 3 formal nights. Most likely the first will be your second night out, the third will be next to last night of the cruise and of course the third somewhere in the middle.

Will evening dress for ladies be more Hawaiin style? Do they have a Hawaiian luau night? Doing this Summit trip next March

The more Hawaiin ports you stop in, the more Hawaiian clothes you will see on people as port by port everybody shops in places like Hilo Hatties. They will likely do a Hawaiin night as a buffet up on deck.
Do they overnight in any port (like Maui)? If yes then be sure to book a Luau ( a real one) as an excursion off your ship.

According to the brochure, there are 3 formal nights, 4 informal & 7 casual for a 14 day cruise. I'm sure there will be lots of Hawaiian clothes on the casual nights.
