Tips on taking pics inside Vegas casino-esp. the fake daylig

[Margotd42]

My son is getting married next week at the Venetian, inside on a bridge over the canal, in the evening.

Has anyone taken pics inside a casino that has the fake daylight?
Do you need a flash?
Do they darken the "sky" in the evening to make it look like "nighttime" (I presume not, but don't know.)

I will also be taking pics inside one of the restaurants there-don't know which one.

I will be using a new Panasonic FZ30, no exterior flash just the built-in flash, a tripod, an external shutter cable, and will be using Photoshop CS for editing later.

Any advice for a semi-Newbie? I have read a lot but haven't taken many inside shots. Suggested camera settings would be great.

PS: I know about the "noise" on the FZ30.
