There is so much to do. Having a pass is nice to do the basics like riding the Maid of the Mist, going in the tunnels behind the falls, riding the transport system, etc. see if they take a
AAA discount or pay before you get there. One trip we did the Amerian side only and the lines were so long for tickets.
Along with the Falls, are the attractions on the main road with Games, arcades, Ripleys, I think we bought a pass for three rides at one attraction. There is the whirlpool that you take an elevator down and walk along the river, there is a butterfly attraction near there, the old museum now has bird sanctuary. You can find coupon books all over for the go carts.
Wow, Great Wolf Lodge, I remember the dozen years we took my Dad and our kids coming where it is. The older man was up and about nearly 24 hrs. dad loved chatting with him each trip.
Another place is Fort Niagara, with the winery route along the way to Niagara on the Lake. It's a short drive and the kids can try grape juice, but the fort and lake are beautiful. You can pick up a lunch and have it along the way at the many picnic tables and wonderful sites.
We use to have late lunch early dinner at the Angel Inn at Niagara on the Lake, it is said to haunted, but never had any luck. But, their fish and chips were nice. A little pricey, but it's the area. Eating in the old open beam room with old furniture is tons of fun.
There is a place that looks like a space ship, I think it's on Lundys lane, breakfast for about $2.99.
OH, be alert you need at least a pass card to get into Canada if you don't have passports. The kids under 16 need birth certificates. i think we paid about $65 for processing and cards. The photos you can get at Rite Aid, AAA or the post office. I took our own and used Internet software to size them. They paid about 20 cents to print at Walgreens.
