Yes, I have been to Pokhara and trekked in the Annapurna area. I'm sure both you and the kids will have a great time.
The locals are so incredibly friendly there. And I remember ordering a pot of mint tea and the lady wondered off up a hill, to return with the leaves she'd collected to make the tea (and at another place they went to dig potatos for us!) Oh, and the scenery isn't bad, either
