I took a Bonine on Sat. night, but DH and DD didn't.
I took my next dose on Sunday about 5:00, but they didn't. DD put on her Seabands though. At 6:00 dinner, we had a vibration under our table. They begged for the Bonine then, but they felt lousy the rest of the evening and didn't attend Hercules. They were fine the rest of the trip.
From then on, at 4:30 or so while we were showering for dinner, I doled out the Bonine all the way around.
We drove home Thursday and every time we took a potty break, the restroom would move. I felt fine as long as we were moving. We all got home and had sea legs, so we took one more nightly Bonine Thursday night.
We've been fine ever since.
p.s. - as long as we were busy, we never felt drowsy in the daytime and slept like logs at night. We were drowsy on the way home Thursday though....just sitting.
