I usually opt for the email instead of the text, but I found that if I give them my actual arrival time that I wasn't getting my email until after that time. So I started telling them I was arriving 2-3 hours earlier than I really am, and now I get the email about 30-60 minutes before my actual arrival time. That makes it so much easier to go directly to the room without going to the front desk. If it matters, my actual arrival time is usually between 4:30 and 5:00pm, so I give them a 2pm arrival time and I've been getting the emails between 3:30 and 4:00. When I told them 4:30, I wasn't getting the email until 5:00-5:30, which necessitated a trip to the front desk.
