Being tactful with wedding invites?

Being tactful with wedding invites?

Here is my previous question:

I need to make mention that our venue is in a way destination. It will be January near a mountain and there are VERY limited accommodations elsewhere. Their other option would be to drive at least 1 1/2 hrs to a larger city. We’re putting a hold on the rooms as a courtesy.

How many people have paid for ALL accommodations for ALL of your wedding guests? I mean, there has to be a tactful way to have some guests pay for their own room.

Maybe saying something like:
“Rooms will be provided on location by Bride & Groom however, a contribution will be greatly appreciated.” Then maybe add our contact information? An email maybe where I can give details?

The wedding will be small (45 people including my fiance and myself and our wedding party). Asking $ 100 for a room is pretty decent. We’re paying approx. $ 25/person for dinner alone, not to mention drinks, and appetizers being extra. If we see HALF the money for the rooms that’s fine but a little would go a long way.
