Parking Solution
We found out that the hotel's parking lot actually offers a week rate of 119 Euro. For anyone staying longer than 3 nights, this will save them money. The hotel was unaware of this possibility, so we had them call the garage and the gentleman at the garage very kindly converted our daily ticket to a week pass. Since we decided to stay a week, this saved us 120 Euros. On the downside, since they aren't very familiar with it, it took two days to arrange the conversion meeting - during which we didn't have access to the car. I'm sure we could have pushed, but we were so glad to have it arranged we happily spent the two days walking.
There also appears to be a park and ride option for 3 Euros for those willing to simply park their cars and not use them. From our research, it is an approximately 20 minute U-Bahn ride to Erdenberg (sp) station where this can be done.
Finally, on a different subject, this hotel has been amazing. Nobody has had an attitude at all, and given how much the lobby resembles a W, it sometimes feels very hard to believe. But everyone is friendly and helpful.
