If you don't like driving a lot, the internal traveler position isn't for you. Every ER has a different way of going about doing tasks in the ER, so it makes it hard to remember the exact way of doing stuff. However, they are understanding of the internal traveler position and are nice about correcting you. Some locations are extremely busy and have high acuity patients, and some are extremely slow and have low acuity patients. So, you may like or dislike either, depends on you, mostly.
