I love doing short staycations as I'm only a 15 minute drive from Niagara Falls. There's so many neat things to do there aside from just seeing the falls which I've seen many, many times.
Some of the things I've enjoyed most are; ride the Hornblower, which is the boat that goes right up close to the horseshoe falls. Everyone gets soaked on that one!:

Zipline close to the falls is another thrilling experience:

The heart-stopper of them all is the Jetboat Ride up the Niagara River river rapids. Talk about getting absolutely soaked lol:
There's also a lot of non-adrenalin inducing things to do near the falls. Niagara Parks keeps the grounds around the Falls in imaculate condition with lots of flower gardens & mature trees. A popular picnic spot for families. Of course there's also Clifton Hill, a place near the falls with lots of touristy stuff for families to do and resturants to eat in.
A short way from the falls is the Niagara Parks Butterfly Conservatory. It's a sort of botanical gardens that houses thousands of bifferent spiecies of butterflys. A most unusual yet beautify place to just wander around whatching them at close range. They'll even land on you if you stay still long enough!
Then up the road away is the quaint little town of Niagara On The Lake. A lovely spot for wandering the shops and coffee/tea houses and a place that showcases the annual Shaw Festival. A series of live plays that runs each summer for a period of time.
The best part for me is I can go home each night and sleep in my own bed. Accomodation anywhere near Niagara Falls is pretty pricey, to say the least
