We stayed in the William Tell room with a rock waterfall shower. It was great, very tacky, but in a good way. The shower was very fun and something that is very unique. I am surprised that there are bad reviews of this place based on cheesiness or tackiness- it's the Madonna Inn- that's the point, you should know what you are getting yourself into! Definitely something to do at least once.
The pool is heated, so although we were there in October, we still went swimming at night (the pool is open until 11pm), which was really fun. They also have two jacuzzis which are nice and open late as well.
The steakhouse was delicious. Somewhat pricey, but the ambiance is fun, and the wine bottles are reasonably priced- which somewhat makes up for the pricey food. The Copper Cafe for breakfast was just OK.
If you are noise sensitive I would recommend calling and asking for a quiet room, as this hotel is off of the freeway, and we could hear the cars from our room (as well as the ice machine, which was right outside the room). We are not noise sensitive so it did not bother us, but it's something to think about if you are.
