Day boat cruising off Denarau

I'm off for a week in Fiji staying in western Denarau island in September. Can anyone please recommend some day cruising tours? I'm looking for an all inclusive type deal - lunch (booze), snorkelling etc. Any recs on places to lazily fill a day or two would be great thanks.

Also - when I get to Denarau is Nadi pretty much the only place I can get supplies - ie some food and drink?

No, there is a small supermarket in Denarau right by the Port

thanks

There is a cruise to South Seas Island, one of the smallest of the Mamanucas. Once on the island all food and drink is included.

We really enjoyed our day trip to Mana Island - great beaches and snorkeling and the island is big enough to do some exploring. The lunch buffet was not gourmet food but good enough for the price. They have a pool and a boutique for shopping.
