Pros
Great staff, friendly environment. Meet lots of people from around the world, including the occasional celebrity. Once past your probationary period you get a staff pass for a limited number of free tickets to all Merlin attractions, worldwide.
Cons
Shift patterns - working weekends and variable early/late shifts can affect your social life outside of work. Due to the London tourism peak season being during school holidays means it can also be difficult to book time off during those periods. Occasional lack of passing on vital work related information (such as 2-4-1 offers) to all departments can lead to customers being provided with the wrong information. This irritates both staff and most importantly the customer who could feel let down by the company and not get the most from their experience.
