Pros
Hotels.com is an established (25+ years) company that is still growing every year. As a "dotcom" company, the work environment is more relaxed, and the company favors innovation and a "fail fast" attitude. Strategies are always changing, and there is always new, exciting work to keep things interesting. As a global travel company, employees have diverse background, so your teammates with have many experiences and perspectives to share. Team sizes are small enough that individuals have a significant, measureable impact on the company. Overall, going to work is enjoyable and employees, from top management to junior level, are friendly and fun to work with; obviously.
Cons
Hotels.com is not the most competitive company in terms of compensation and benefits, but they are from the worse as well. The Dallas metro area is a standard suburban sprawl, which may be considered non-ideal to some, though the drivability and low cost of living make up for that.
