Hotel Information Question

I have rooms blocked at the East Norwich Inn...... They're policy is to reserve the room at the normal rate of $140, and upon checkin guests will be charge $120 if there are 10 rooms or more booked. (which I'll definitely have)

What sure I include in my invite as far as hotel information? I don't want to say the discounted rate, because when they call to reserve the room that's not the amount they'll be told.....But, I feel I should let people know it will be discounted upon checkin......

Just having some trouble figuring out how to word it.

Any suggestions?

That's kind of a weird way of doing that. Must make for a lot of confusion at checkout time.

I'd note the rate at $140. I would rather underpay.
If you know who is staying at the hotel, then just let those people know that the rate MAY go down based upon the number of rooms that have been confirmed. Ask your hotel for a list of confirmed reservations, and take it from there.

What if I put 'guests will be charged a discounted rate upon check in'....and not put a rate down?

Hhhmmm.....

Though, I could add 'please check our wedding website for more details' and put the rate change info in there right?

I would put the $140 rate and then closer to the date, if you have 10 booked, let as many of them know informally that they will be charged less at checkout.

I put the rate on the hotel card in my invitation -- it's basic information that people will want to know when considering whether to book there. It saves them a phone call.
