What time does your flight land? Typically they advise that it can be a while until luggage arrives - like 5 hours - so if you arrive late, I'd get it yourself. I think some people have had luggage delivered late - after midnight - and others have had it held at Bell Services... just probably depends on the resort.
If you arrive after 10 PM, then you need to pick up your own luggage.
We have used the ME luggage delivery for all our other trips and been happy with it - but we've arrived at 1 PM or so in the afternoon, so plenty of time for luggage to be delivered. This time we arrive at 9:30 PM (yawn!) so we'll pick it up ourselves.
