I have just recently decided to take a trip w/ a friend of mine to Niagara falls. We are staying @ the Marriot Fallsview, and have reserved a fallsview room. We will be there about 4 days, and would like to really enjoy the trip. Any tips on things to do? We'd like to do the whirlpool jet boats, and take the Cave of the Winds tour. Any other suggestions? Also, does anyone (a local maybe?) know the best way to get from the airport to our hotel? Does Marriot have shuttles from the airport?
