Daylon, you are not an idiot. If you haven't been there, then you don't know and I should have been more clear.
The place that you picked out to stay is on the north side of the island. Even so, it is across the river cut from town. It takes a hand ferry or a water taxi to get that resort (or any other resort north of the cut). The hand ferry stops at 8 pm and water taxi's cost some money and are bit inconvenient anyway.
So I'm just thinking that two single guys that enjoy some nightlife, would want to stay closer to town with more access to same.
I notice that the resort that you picked out is a condotel type. In other words, it has a kitchenette and a sitting area. Do you guys really want that? A pool? You are only staying for a few days right?
Me, I do like a condotel, but if I were only staying a few days, I might not be so concerned about that.
Here's some places in town to look at: Paradise Villas (get one on the beach side not the garden side), AquaMarine Suites, Mayan Princess.
Close to town: The Palms, Ramon's, Sunbreeze, Belizean Reef Suites.
The thing is if you are going to be diving and only for a few days, then check out the dive operator, Amigos del Mar. They run a pretty slick operation, have great boats, good DM's and I have as much fun on their dock as I do diving or hanging out anywhere on the island.
And if you stay close to town, in the evenings you can walk to everything and then easily stumble home.
A fish and a bird can fall in love, but where will they build their nest?
