We got our room here after our wedding. Beautiful views and underground parking are pluses, but they weren't able to give us a block of rooms, and required a 2 night minimum from us and the quests who booked there
We were only able to obtain rooms for one night here, so fewer of our guests stayed here, but those who did had no complaints. It is very professionally managed and great for frequent business travelers who were able to book online and use loyalty points, etc.
My guests loved the hotel. The location is great for out of towners. You can walk most places, plus your right on the lake, so most rooms look out over it.
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.
