What wording did you use on your accommodation card?
I had the card worded as, "for our guests' convenience, we have reserved a block of rooms at....". This is the wording on the sample from the invitation company, but I was thinking that makes it look like we are paying for the rooms (we aren't). Listing the price of the room or even using "at a discounted rate" seems tacky to me. I also don't care for the word "block".
Did you use a different wording? Am I overthinking this?
