Turbo,
Hell yeah. You should definitely start. I've been surfing for 20 years, yet due to a lifestyle change, (flying career) Ive been landlocked for the past 3, and have packed on the flab (over my great abs)

. Hopefully my Poi belly and I will be living in Hawaii very soon as I am in a pool, anxiously awaiting a class at one of the regionals over there.
I think it'd be alot of fun to go surfing as a family.(Its fun enough when you're all by yourself). Stick with it. It takes alot of time and dedication, but the rewards are incredible. Ive never surfed Waikiki, but from what I've seen, it looks great for learning. Warm, clean, clear water, mushy waves with enough push, looks ideal. No wetsuit. Ahhh.....
Secretly learn to surf on your layovers in Waikiki, then when you return to FL, tell your daughters that you finally want to learn to surf with them, and blow 'em away when they see that you are a "1st time" natural.
