Just as a follow up the Hilton was nice. For some reason we had access to the executive lounge and it was nice to get some free drinks, snacks and breakfast.
The room was nice. The only negative was that the seam in the wall paper about 4-5 foot up the wall was coming off the wall. Kind of unsightly for such a nice room but it wasn't a big deal to me.
The S-bahn was easy to navigate. Finding the elevator up to the Hilton proved tricky to us. We also had an adventure in figuring out how to buy a tram ticket when we ventured out to the Nymphenburg Palace. Didn't realize they could be purchased at the same places as train tickets.
Anyhow we had a great time and the snow didn't mess up anything for us.
