Cruise secrets: Why you should never use this queue when disembarking

It is also advised to avoid the casino onboard ships during a cruise.

The odds on a ship is often much worse than on land, due to the lack of competition.

Las Vegas, for example, has to compete with hundreds of casinos, therefore, can offer lower rates.

Blackjack onboard can be “paying 6-to-5 instead of the more usual 3-to-2 [on land],” according to cruise website Cruzely.

While this may not seem like much of a difference, this could result in a difference of a $10 bet paying “$12 on blackjack instead of $15 under the typical rules.”.
