Pros
It's an easy job for decent money. For the most part you are left alone to do your job. One great benefit is being able to stay at any of the hotels in the corporation for free or very inexpensively, if you can find one available. If you like talking to people this is the job for you. You'll make great friends that will last beyond your employment.
Cons
Once a month meetings with your supervisor that is full of discouragment, negativity and bad reviews. If you can't sell enough hotel rooms in a month, you are written up. Yes, it's your fault if you get more cancellation or modification calls than sales calls! Information about the hotels you are trying to sell is very minimal. The plus is if you have been to that particular city before and know something about it otherwise good luck. Their protocal for a phone call changes monthly. You don't know what your supposed to say to the customer anymore. And if you need to transfer a customer to another department, good luck finding the right transfer number.
