Hi Sue, we just got back from West Thompson Lake last weekend, all the electric sites have 30 amp. This is our 3rd trip there in the past 4 yrs. I run my A/C heavily... never had an issue or have any of the camp host ever say a thing about the power.
We always take our kayaks with us for the lake. Also they have miles of easy & scenic trails around the lake.
As far as Witch Meadow I think we actually stayed in site 186 back 16 years ago in our popup, "If" I remember that area the sites were some what small but level ( mostly because the sites were level to the lake)
A lot of CT campgrounds have gray water hookups. what you need to buy is a 3inch X hose adapter that fits right on your gray/black water outlet on you trailer. When your at the campground then just run a cheap/old garden hose to the gray water connection on the ground with your gray water "only" valve open. camping world sells the adapters or any local RV parts store...there very common.
Witch Meadow has had some power issues with the larger (50amp) RV's, just be aware.
Don't forget to check out the reviews on both campgrounds at
