The Hilton is one of Madison's nicest large hotels. The honeymoon suite was great. However, the cut off date for guests getting the wedding rate was way too early (4-6 weeks before the wedding), and so many people had troubles with the discounted price. Try to arrange things so that the front desk people will give your guests a discount when they call. That was the biggest problem (and it was pretty big because before your wedding, you do not want to be making calls 2x/day to a hotel). There is an airport shuttle, which was a big plus.
