Hi @Nina5 when the reservation was confirmed, your guests were given your contact information. It is not unusual for guests not to reply to questions about arrival time until the last minute. I have some guests arriving on Saturday, sent a message yesterday asking, among other things, to let me know their estimated arrival time. Haven't heard back...they are travelling so probably haven't check their email yet. Don't worry, your guests will eventually get in touch with you.
By the way, I looked at your calendar and except for 3 days in January, you listing is completely unavailable. Is that intentional?
