Hey, we're thinking of heading down to Belize for a couple of weeks. Of course we will do some snorkling and such, but can someone give us some nice lodges that offer wildlife viewing tours. I get bored at night, so I'd prefer places that also offer night tours or that can be done as a day trip

You might want to head to the Cayo district. Check in at Eva's for which tours are going while you are there or if your are staying at one of the resorts they may offer their own tours or be able to recommend some.
I am fairly sure that the Lodge at Chaa Creek has tours but they are fairly pricey. Maya Mountain lodge also has tours and is a little more reasonable. Trek Stop orPacz Guest house are more basic but should be able to help you.
Nearly all the lodges in Belize offer wildlife/birding tours, including night tours. (People staying at the lodges tend to go to bed early, though, due to the heat, being active during the day, and a big meal and drinks in the evening.)
Among the best lodges for wildlife tours are:
Chan Chich Lodge, Gallon Jug (in Orange Walk District)
Lamanai Outpost, Indian Church (Orange Walk District)
Lodge at Chaa Creek, near San Ignacio (Cayo District)
duPlooy's, near San Ignacio (Cayo District)
Pook's Hill Lodge, near Belmopan (Cayo District)
Hidden Valley Inn, Mountain Pine Ridge (Cayo District)
Crystal Paradise, near San Ignacio (Cayo District)
Mama Noots, near Dangriga (Stann Creek District)
The Lodge at Big Falls, Big Falls (Toledo District)
There are lots of others.

I stayed at Pook's Hill in November 2006. I really loved it there. I'm fairly certain they do night tours. They do an early morning bird watching hike as well. They do have a web site. I highly recommend them.
We loved the 3 places we stayed in the Cayo District - check out our photos and travelogue (with live links, find the link to it on main page of the Belize collection) if you're interested. Overnighter to Tikal highly recommended (additional Tikal photos in the Guatemala 2007 collection).
