HI, Victoria. Hope you'll have a great time at our "home" park, Shenandoah. Which CG are you hosting? Perhaps we'll see you as we try to get there every spring.
When we last went to Niagara, I took the longer Interstate route in order to avoid the many mountains in PA. So I took I-81 up to the PA Turnpike, then west to Pittsburgh, then North. I meant to break up the trip, but drove it in one day - which is not my preferred way.
What I would do next time is stay a Penn Woods (the Airstream park east of Pittsburgh. Then it will be an easy trip up to Niagara.
We stayed at the KOA on Grand Island and thought it was just fine. The people were real nice and we were able to catch the tour bus right at the campground. Since we don't do many tours, we signed up for the combo package that visited both the US and CAN sides; I'd recommend you do that if you can find it in your budget. BTW - We met some folks who were staying at the Good Sam and they said they wished they had stayed at the KOA instead.
After Niagara, consider driving up to Algonquin Provincial Park. Just be sure you have reservations if you want to stay over a weekend.
Somebody, please, point me to the road.
