My FH and I want to offer a shuttle service from one of the hotels where we have a room block but I'm struggling to figure out how to estimate what size shuttle we'll need. For context, we're getting married in April in NJ and will have either 150 people or over 200, depending on gathering restrictions (wishful thinking, it will definitely still be restricted to 150...c'mon Pfizer and Moderna vaccines!!). The venue is at least 1 hour away for all guests so not all will spend the night at the hotel but for those that do, I don't want people worrying about drinking and driving.
Those who booked shuttle service, how did you determine how big of a shuttle to rent? I'm worried about booking one that's too small but I also don't want to pay for one that's larger than we need. Also, how far in advance did you book this service?
TIA for any help you can provide!
