Unfortunately, no. The parking lot has limited space, and cannot accommodate both the guests that are already checked in, as well as guests that will be checking in later that day. Additionally, it becomes near impossible to plow the parking lot during heavy snows when the lot is congested. Your best bet is to park at Top Of The World (free) if you plan to ski/ride during the day, then come over to Mountain Lodge for your 5PM check-in.
