Yep, they have 3- to 3.5-hr programs for the Struve for $125 per person. This does not include lodging, but rooms are $88 per person (when available) for Special Viewing Program participants.
These programs are limited to about 15 people per night, max, and they generally select 4 to 6 targets per night, depending on the number of participants.
The rental I mentioned earlier includes up to 16 people and is an all-night program where you submit a target list of your own in advance and they select what's available from among them. You also are guaranteed a spot in the lodge and meals. You can reserve one or two nights, depending on availability. My times there have been between October and April and we have managed up to 40 targets a night when weather permits.
For either of these programs, demand dictates you should make a reservation at least 60 days in advance. Generally, the overnight programs are sold out within a week of the announcement of available dates.
