I had to change the cache container to give it more camoflage because it got muggled twice in a week. The altitude was changed and it is much harder to find. I upped the difficulty a little and added a hint.
The cache is at N 44 5S.SSS W 093 15.PPP.
SSSS is the number on the blue and green sign nearest American Boulevard minus the number of large blue and green signs outside the building.
PPP is the approximate number of parking spaces in the lot. (Round to the nearest 100)
* * Update * * - As of November, 2015 there is construction going on and it is no longer practical to estimate the number of parking places. I had found the information on the hotel website before, but I don't see it anymore. Here is a BIG hint to help you with that part: the number you are looking for is between 301 and 499.
