Hi @Alex6513
Many guests don't know how to access the arrival guide.
For that reason, many hosts also create a quick reply with arrival details (you can decide whether you want to schedule it or send it manually).
This probably doesn't fully answer your question, because I don't usually use the arrival guide at all. I prefer to manually send arrival instructions only after guests have confirmed their estimated arrival time.
But you can use both methods to make double sure they have the arrival details.
