"We debated adding Accommodations cards to our invitations since we have a website and assumed people could get their information there. However, I am so glad I changed my mind! These are perfectly matched to my invitations and they are the perfect size...about the same size as the response card. They shouldn't drive up shipping costs when sending the invites. I modified the card to say the name of our hotel block in the top box above the hotel information and used the bottom box (under the address) to include information about the wedding website. I love that someone edits each card personally to catch minor grammatical errors, etc."
"I ordered this card with hotel information for my guests. I had forgotten to order it with my invitation order, so I went back in on Wednesday night to order, and I had them by Saturday with express delivery. It was wonderful to have them so quickly. I didn't have to delay sending out the invites with such a quick turnaround time."
"The card turned out perfectly. The designer even made some helpful suggestions about spelling out words included in the directions."
