we only got lockers at the MK, but I imagine they are pretty much the same all over the parks. The MK lockers are under the Main Street Train Station, they cost $7.00 - but $2 is refundable when you turn the key back in at the end of the day. They are really roomy - plenty of room for jackets, ponchos, etc. We stored our kids' regular clothes after they changed into costume, plus extra water, etc. Have fun!
