We are going on the Alaska cruise in August and would like to take our daughters whale watching. They will be 5 & 7. We are concerned about seasickness. We took them on a glass bottom boat in Key West in June and it was really choppy and really hot and humid out(might have been part of it) and both the kids lost it. What has your experience been with your children? Are the seas generally calm? My wife is freaking out and is afraid to take them on a boat again. Please help.
