Short Answer: Probably not.
Long Answer: It is unlikely that you will get motion sickness aboard Groove Cruise. These ships are huge so it takes some pretty sizeable waves to get them to rock enough to cause motion sickness.
However, slight motion does occur and that could cause some people to feel the effects of motion sickness.
Rest assured, the staff aboard the ship will be happy to sell you motion sickness pills in the event you’re not feeling well.
I suggest that if you feel like you may be subject to motion sickness, you take proactive measures against it.
I, personally, am prone to getting motion sickness, so I’ll share with you what I know about preventing it. Disclaimer: I’m not a doctor. Please consult your medical professional before taking new medicines.
While motion sickness pills come in different names as well as pills or chewables, I have found that there are generally two main ingredients used to fight motion sickness, dimenhydrinate and meclizine.
They both seems to work, but the main difference is that dimenhydrinate may cause drowsiness while meclizine works while causing less, if any, drowsiness. I prefer meclizine-based pills. I just pick the cheapest one at the store, and take one every 6 hours or so and I’m good to go.
You may also want to consider the patch that goes behind your ear. I haven’t use that personally, but I hear good things.
Again, it’s unlikely that you’ll get motion sickness, but at least you now have some info on how to prevent it!
