A group of us will be traveling to Niagara Falls to celebrate a friend's 30th birthday party. We hoped to go there from Thursday through Sunday at the end of February. The ideal would be to have a nice hotel suite to maybe accommodate the 8 girls (we can sleep on couches), spend a day at the spa and another day doing a wine tour. Any recommendations on affordable suites ($100-$175/night), good spas, and full wine tours that provide transportation? Also, what is a good area to go out at night ?
