if you are staying at a value resort - because they have few people for luggage service (different name here) - just bring your luggage to them - same area where you get off the DME bus.
now you can call them and they will come get it - but it takes them longer.
they are not consider a bell service. One good thing about it - they can take your luggage when you are not there. they don't require a tip. but a tip is always nice.
if you aren't there - make sure - that you leave good instructions - your new resort, your name, your reservation number at the other resort, cell phone number where you can be reached.
