They provide the equipment. For tubing no lift ticket needed. You go up with a ( free) "magic carpet".
Tubes are provided and you only need to purchase a lift ticket if you are skiing or snowboarding on the hill
They will provide the tubing equipment. In fact you are not allowed to bring your own sleds/tubes into the area (so you can save space when packing). It's a short walk over from the entrance but feel free to save the steps by taking the "shuttle-trolley" over.
They provide tubes at the tubing area. Not sure what Mountain adventure is, so not sure if you will need the additional lift ticket purchase or not.
