We were in Niagra Falls a few weeks ago...stayed at Niagra Falls KOA. Not super fancy and back in spaces were a little tight (pull through sites had more room), but the grounds and showers were clean. During the day, we left after eating breakfast and weren't back until the end of the day, so we didn't spend much time there, but they do have some fun things going on during the day for the kids. We towed our Jeep and used that to get to and from the falls, but the WEGO shuttle has a stop right at the campground. We didn't need it from the campground, but used it up and down the river to different attractions. Shuttles were large, clean and air-conditioned. My suggestion would be rather than unhooking and driving to the falls, leave your MH at the campground and take the WEGO wherever you need to go. If I remember correctly, an adult pass was $18 for two or three days, unlimited use...well worth the money.
