We were there last month Jan 16 - 24, staying at the Wilderness Lodge Villas. First of all, it was very cold (3 nights below freezing and in the 40's during the day. We had two days with temps in the low 60's). I was VERY surprised at the crowds (mainly made up of tour groups from South America and lots of families with stroller aged children). We went to AK the Saturday of MLK weekend and arrived right after rope drop. We fast passed the Safari (had a two hour window to wait and come back) and stood in line for Mt. Everest, waited about 20 minutes and that was as good as it got. We ended up going back to the resort after lunch. It was like that all week - wait times were crazy, even with fast passes it was a 2.5 hour + return time. I wasn't expecting this in January, let alone a so called recession, hahaha! It was like that everyday with the exception of one. It had gotten down to 28 degrees the night before...we hit the Crytal Palace at MK the next morning for Breakfast. The park was EMPTY until after lunch - it was wonderful!!!
Still had an awesome time and we go often enough that we don't have to cram everything into one trip. Would I do January again? Maybe, if it was warmer, hahahaha!
