I don't know if we discussed this. Sorry if we have. So much to digest, all at once.
Can the owners have a Balance Due Email and a Security Deposit Due Email to send out? It can be an optional thing, if not everyone wants to do this. My guests really appreciate these letters, even though it will automatically be done now (if paid via CC). Especially, the ones paying via check, appreciate these emails. I send them out 2 weeks prior to 30/60 days prior to arrival. Plenty of time for them to put money in their account, if need be, and send the checkout in time.
