This is the most relaxing and awesome, first time whale watching experience I've had. The crew was very knowledgeable, friendly, and professional. They made sure that the whole trip was something to remember. My group was lucky enough to see various sea animals that comes occasionally to Monterey. Overall, I fully recommend booking your trip with Discovery Whale Watch.
I've also read the 1 star reviews and i think that it's not fair to state that experiences were awful because of seasickness. If you can't handle the sea (it is the pacific ocean with its rough waters)then don't book a trip and whine about it later.
