so should I have my group take something before getting on the ship or just wait it out and see how they do, suggestions anyone?
I tell EVERYONE, take bonine (NON-drowsy dramamine) about an hour before stepping onto the ship and carry ginger capsules in your pocket. I'm very well known in my family for having thrown up all over Europe. We travelled by car a LOT and I got sick every single time. Even now, I have to be driving, not even a passenger up front, or I get queasy. Space Mountain is a no-go for me and BTMRR is pushing it.
16 foot swells that did cast members in on our cruise did not faze me. I had a small buzz from the bonine, but did fine during dinner and the show. It was so bad that during Hercules, Hades had a line that brought a small laugh from the audience and he said, "Hey, I realize there's only 25 of you out there, but STILL, you can laugh louder than that!"
The seas were BAD. People were passed out on deck 4 and there were "protein spills" all over the deck, bad. I went back to the room, but we were all the way forward, so it was like an amusement park ride, so I did start to get queasy. The idea is to keep the queasiness from even starting. I went back mid-ship after taking some ginger capsules and was fine. After the first night, everyone got better, but I still kept up the bonine/ginger regimen for 3 days AFTER we got off the ship.
BTW, it's also a good idea to take a bonine at home in the evening just to give it a "trial run" and see how you do on it. It doesn't knock me on my behind like dramamine does, but it does give me a buzz, so I don't feel safe driving with it.
