The one thing I would suggest is pay the extra (if you can) to have each person ride their own ski. I rode on the back with my husband and it was AWFUL! It was hard to hold on and I almost fell off the back several times. I think it was my husbands way of doing me in for the insurance money!
I agree 100%! It's very hard for the driver to navigate the craft with someone holding on. I had my 8 year old Granddaughter behind me last time and that wasn't too bad. Still, you just don't have the control as if you were alone. HANG ON
I 'm originally from Chicago... You can jet ski on Lake Michigan. (you need a dry suit most of the time though... )
If you insist on doing this on your cruise, don't get a Jet Ski, get a SeaDoo type watercraft where you are sitting on it instead of trying to stand up. These are safer in my mind. The wife rode a jet ski once.. was just getting the hang of it when a boat passed in front of her. The jet ski stopped dead when it hit the boat's wake and the "handle bars" nearly impailed her. She had a bruise on her thigh bone from the impact that took a very long time to heal. I can't imagine trying to ride one in the ocean surf.
Don't forget there are no brakes on a jetski. Also when turning you have to stay on the throttle. If you let go you fall over or go straight. If there are ameteuers around (you included) think twice before putting yourself in that environment. Get travel insurance if you're considering it. It'll pay the doctor bills.
They refer to all "Seadoo" type jetski's as just jetski's. I don't think they even make the standup type anymore. I think they called them "Waverunners". Jetski's are a blast if you are on them by yourself.
