. . . WL makes you leave your luggage with them and they bring it to your room. I was furious about this since I never did that with any other Disney resort. We always just get a cart but they said they couldn't let us do that . . .
1) You are NEVER mandated to leave your luggage with Bell Services
. . . you may always keep it with you and tote it yourself
. . . this is weather you bring it to the hotel or use DME
. . . they may ask strongly, but they will not insist you use bellmen
. . . it is your option
2) As for the luggage carts at Deluxe and Moderate resorts
. . . they are for the
sole use of the bellmen
. . . tips are their pay
. . . without the carts, no tip
. . . so, you either tote your luggage or use bellmen
. . . it is your option
3) For previous above posts
. . . luggage does come up missing at resorts all the time
. . . usually it is eventually found, even if it was delivered to someone else
. . . occasionally, luggage is broken into while in Bell Services
. . . unfortunately, people are people, even at WDW
