Standard to use Bell Services? I wouldn't claim that. Many people do because they are willing to pay to not handle the luggage. But many people don't either - luggage has wheels! And I especially dislike Disney that won't hang with you while you check in and then take you up to the room. You give it to them then they store it then you have to call from the room to get it delivered. If we can handle our luggage ourselves, and we we almost always can, we just keep it with us and don't waste time with Bell Services.
But they'll help anyone that will pay them.
