Keep in mind the following if you're planning to board The Big M for some gaming:
All passengers must be at least 21 years old to sail.  Photo ID is required at check-in.
Dress code is casual, but no swimwear, offensive material, visible undergarments, torn or soiled clothing, and visible offensive tattoos are allowed.  Yes, it's Myrtle Beach, but try and look just a little bit presentable.  Shirts and shoes are required at all times.
No guns, knives or weapons are allowed on board.  Keep that stuff at home.  No outside food or beverages are allowed, either.  No photos are allowed in the Casino at any time.
Women who are 24 weeks or further pregnant may be refused passage.
Cruises will be canceled for high winds and seas.  Safety first!
