Interestingly enough, wait times for Forbidden Journey were unusually low last weekend at night. I'm not sure if that will sustain into next weekend, but a nighttime ride near park closing might be your best bet.
If you could dump anything on your list at night to save time for Grinchmas, it'd be the Nighttime Studio Tour. If it has a low wait time during the day, take it and save time for Forbidden Journey and WaterWorld. The rest can be done whenever without affecting show quality.
