90 minutes is the outside arrival to your resort. Average is about 60 - 70 minutes. On our last trip, we arrived at 6:10 PM. We got to our resort at about 7:00. We arrived during the weekend of record rainfall. Our luggage didn't arrive until close to midnight because the rain had caused such a delay, so that certainly isn't the norm.
With that being said, pack everything you need for the night in your carry on. If it starts getting too late for delivery, call Bell Services and have them deliver your bags in the morning.
