helocopter vs seaplane?

[Sarilou99]

I'm going on a cruise next year to Alaska for my mom's 50th birthday and my hubby is REALLY excited to do lots of land excursions. However, I am really nervous for my bladder, as I'm sure you can understand.
He wants to do either a helocopter or seaplane ride. I am worried of the vibrations because they really get to me. Does anyone have a recommendation?
thanks.

I've always wanted to ride in a helicopter, even though I'm afraid of heights, but I'd also like to do a seaplane. When we were in Hawaii, my husband wanted to do a helicopter ride over the volcano eruption; at the last moment, I chickened out so he found a wonderful spot in the shade to park and I read a book and took a nap while he went with my encouragement.
