Been there 2 weeks ago. Single tube is $8 and double tube is $12-13 if I remember correctly. You need pay $2 deposit fee for each tube, which will be refunded once you return it at the end of the day. PS: Go for those double tubes first, as they'll run out very soon.
The standard price is what the others posted. $10-$15. If you are a six flags member (monthly payment vs one time ticket) you get discount depending on your membership level.
Single is $10 and a double is $15. There is a $5 deposit that is given back to you when you return the tube and show your wrist band.
Single - $10 Double - $15 Both $5 despite
