just leave your luggage with All stars and have it transferred to BLT - then go to the parks or be like me and go check in - so take the bus to the MK then walk or take the monorail to BLT - check in - then go to a park.
that say would bring with you - back pack will do anything that you can't live with out - phones, computers, sunscreen, prescription drugs, non-prescription drugs - if you might need them - sometimes it will be 3pm before your luggage is brought to BLT - so be sure to call when you get there - so they can deliver. they only deliver w/o you being there when it is DME - anything else they except a tip.
