Durango, Colorado advice

I need some advice on a *family* vacation in Colorado?
We are going the last week before Memorial Day and I will be
taking my family (wife + 5 kids - baby to 9 years old +
mother-in-law aka babysitter).

So, it is not a pure fishing trip, but I want to stay somewhere
where I can fish close by, you know a few hours here, a couple
of hours there. Plus I need other activities for the kiddos.

We've more or less settled on a cabin around Vallecito Lake.
The lake looks to be good - I have a fishing kayak. And there
seems to be several streams, creeks, and small rivers feeding
into the lake.

Any advice on accomodations at this location? There seem to be
several to choose from. Any fishing advice? Optional Colorado
locations?

Cordially,
