I'd like to add a line in my rsvp cards to ask guests whether or not they'd like to utilize our shuttle for the day-of. It will help us get a better idea as to how many buses we will need (we're providing buses that will take guests from the hotel to the venue, and then back). The wording for this needs to be concise. I was thinking of something along the lines of adding a checkbox and then the words "Will require shuttle transportation". Does this sound OK? Any suggestions would be appreciated!
