I thought it was very efficient. We went straight from the plane to the ME desk and were loaded right onto a bus to the hotel. About two hours later, our bags appeared in our rooms. I had planned ahead with anything I might need for the evening in my carry on, just in case! On checkout day, I left my large suitcase with the resort ME desk and was even given my boarding pass (Delta), checked my carry on with Bell Services and went to the park. When I returned to the hotel, I retrieved my carry on, boarded the bus to the airport and went straight to security at the airport, bypassing the airline check in.
I've been using Mears for years, and this was way more efficient!
