Where to stay For four nights this July in Manchester, VT with two children and two adults?

Do you need a place that is not musty?

There is quite a range of lodging choices from the 5* Equinox Hotel to family run motels. Palmer House Resort doesn't allow children under 12. Look at Northshire Lodge, Inn at Willow Pond.
www.visitmanchestervt.com will give you lots of choices.
You can also look at Bromley Mountain and Stratton Mountain Resorts 20 minutes to an hour away..

I think Airport parking might be talking about Manchester NH not Manchester VT

No, he's talking about the UK. I've pushed the yellow triangle, in any case.

OP said Manchester, VT.

OP was talking about VT, HappyTrvlr, but the post that was removed was talking about airport parking in Manchester, England. Actually I'd love to buy airfare to VT, then find myself in England. . Cool!

Manchester View Motel

Rent a condo/apt/house. Go to vrbo.com and see what hey have in Manchester, VT. You didn't specify the ages of the kids or nightly budget so whether two-double beds in one room or everybody getting their own room you need to evaluate this option. The advantage of the condo/apt is access to a kitchen where everybody can fix themselves a snack/breakfast/grill. Eating out all meals in Manchester, VT will put a serious dent in your budget....
