My husband wants to take my kids on an adventure vacation. He is 55, a heavy smoker and is recuperating from a very serious illness. My kids are not into sports. My son will have just turned 12 and my daughter is 19. I am wondering if this vacation is too extreme for people who are not sportsy or even “active”. Please help me if you can because he has to book tomorrow. Thanks so much. The only person I have talked to told me that class two rapids will put them upsidedown for sure so that would be scary and that they will need more than just nominal instruction.
