Hey there @dcvacationhome 👋

While I do not have a personal experience to share with you I can offer some advice that I have been able to learn from other Sellers in the lodging or Bed and breakfast industry. My advice is that while online payments may be convenient, the best way to secure these types of transactions is by attaching a Square Contract to the payments and making sure that your refund policy is clear and concise. This will potentially help avoid losing any disputes or chargebacks.  Here is some information on Attaching Contracts to payments in Square.

I hope this information is helpful!
