I’ve done two EF tours, one in high school, and one in college, and I would recommend them, though I went with school groups and I’m not sure if you can sign up for one as an individual. The only con with these tours is they tend to take you to the same kind of restaurants over and over, but they do provide you with plenty of time to explore on your own, so I would use some of that time to seek out more exciting dining options. Is he particularly active? REI has some tours that look just amazing, and for all skill levels, so if he likes to hike, bike, kayak, or all three there’s all kinds of options.
