Our BnB is in a major college town and May graduation is a five-figure event over three days. We'll be renting out nine rooms. We plan to charge it at the start of the year (guests are aware of our policy). Credit card fees will be around $300-$400 for this. Thoughts on asking our guests to just send us a check instead (minus the deposit that we've already taken)? It would have plenty of time to clear.
