a great first rental experience in Ireland

Like: the person who helped us with our pick-up was friendly, patient with my questions about driving, and even willing to answer questions about tourism.
Dislike: after checking in at the terminal and taking the shuttle to the lot, we hopped out of the van and were not directed to the right place. as a result, we ended up standing around inside at the desk for another 20min before someone ascertained that we had already checked in at the terminal, and that we only need have talked with someone directly outside the van that dropped us off in order to get our vehicle. why had that not been clearer to us, we wondered? we also thought it would have been good to mention the park-and-pay system before we left. i googled ahead of time but didn't come across it. instead, the advice given to us by the Enterprise employee was to use parking lots, which is ok but only half the story. eventually, we figured it out, but it would have been a good tip to give.
