Answer:
The answer is: No
Explanation:
In order for this clause to be enforceable against Malik or his friend Jecala, they should have been notified about it before they purchased the ticket. Oceanfront is changing the contract terms unilaterally without notifying the other party and that is not legal. A contract (the ticket is a type of contract) is an agreement between two parties, not one party imposing his conditions over the other.
