No worries here. We were there the last week of January last year and it was not crowded at all. Last week just goofing around I couldn't find much for January 15 and 16 but plenty after that for the rest of our week. We are going a week earlier because of those darn annual passes. We are AKL (annual pass rate) for MLK weekend and figure if it is busy we will just kick back at our resort. With the extended evening hours at times we figure we will be okay. I just worry a bit about the weather flying out of DTW. We get ice storms in January at times.
