Yes! A small group tour like this is perfect for people that have not used nut-crackers and rope tows before because your Tour Manager can spend the time with you to give you loads of instruction and advice.
Everyone struggles at the start using rope tows so it's just a matter of being persistent - everyone has been in the same situation before and it is expected it will take you at least a few attempts until you get the feel for it. It is all part of the experience!
