We like to think that if a guest has just arrived at your hotel, they have not experienced enough to have a true sense of how their stay is going so far, which is why you are able to set a delay before the first message is delivered to guests after they check in.
The amount of time to wait is subjective and truly a matter of personal preference. We like to recommend giving at least enough time for guests to reach their rooms and settle in. 80% of hotels will wait between 1 and 3 hours, but we do provide options as short as 30 minutes and as long as days.
