My question involves a consumer law issue in the State of: NEVADA

If I signed a contract with "SWAT - Summer Winter Action Tours" that stated "that they reserve the right to change the vacation destination" is that binding? How can a company change the destination of a chosen vacation without the persons consent? My son does not want to attend the new destination and only signed up to go to the original destination. They say that there cannot be a refund because we signed the contract. Even though it is in the contract, it doesn't appear to be a statement that has legal precedence. It seems comparable to putting a statement in a contract that says "we can't be held liable for any changes that affect your trip". There is no way that can be held up in court. But then again I am not a Lawyer, so any help would be appreciated. Thanks.
