Could be the kids. I imagine they could be annoying on a cruise.
I vacation often with my grandchildren to Disney and I can say I want my space often.
Strangers often find our children annoying even though we don't.
My friend told me to start cruising. He said he LOVED cruising. He stopped and said except for one. The Disney Cruise. He said kids were all over the place screaming, dropping soda, food all over in the dining room etc. He said the food was "vile". I laughed so hard. I said that was an extremely harsh term!
