The culmination of the film comes when Tammy and her grandmother finally reach Cave of the Winds, a dream come true Pearl, whose father had always promised to take her.
Cave of the Winds is a tourist trap worth visiting at least once your life. The tour brings you right into the mist of the Falls which makes it exciting, albeit a little scary at times. For more information or to get tickets, visit niagarafallsstatepark.com.
No road trip with the grandparents is complete without a little history. Old Fort Niagara is an 18th-century fort overlooking both Lake Ontario and the Niagara River. Tours bring you through the original buildings where Native American, French, British and American soldiers lived and worked from the 18th to the 20th centuries. They even offer a senor discount.
If grandma's up for a little kitsch, check out the Haunted House of Wax, a throwback to old amusement park attractions with electronic wax people and monsters that move. A highlight of museum is the decapitated Dracula dummy positioned so visitors can prop their own head on it and take a photo (in front of a backdrop of Horseshoe Falls, of course).
If you don't think granny will appreciate the cheese at the haunted house, you can try an old standby - the Fallsview Casino Resort. Grandmothers seem to love slot machines and just in case yours doesn't, they also have aromatherapy massages, all you can eat buffets, and nightly entertainment. You can even book a bus trip for you and your gram to the casino from just about anywhere in Ontario, Michigan, Ohio, Pennsylvania, or New York.
Or, if your grandma isn't into traveling, Tammy is on screens across the country right now.
