This is the fourth time our family has used Gren Tours and the company has never let us down. Glen was our tour guide and to say he was fantastic would be an understatement! We have been to London before so the challenge for Glen was to show us some new and interesting sites of London that we hadnt previously... More

We were so lucky to have the chance to tour London with Glen! Our family of four spent an entire day with him where he effortlessly introduced us to this magnificent city and its charms. He was attentive, informative, humorous, and, most of all, very interested in making sure our two teenaged girls remained engaged:). With only 4 days in... More

Great tour of the main part of the city. Glen was very accommodating to our wishes, too. We wanted to added Harry Potter, Beatles, and Olympic sites, and he just took it all in stride. Perfect way to start off a visit to this great city. More

We recently visited London and used Glen's service for an airport pickup and overview tour.

We also appreciated being picked up in a vehicle that easily accommodated four adults... More

I found excellent reviews on Gren tours on tripadvisor, so I decided to book it, as I was planning a school trip for my high school students. I sent an email, and got an immediate response from Glen, and not only did he confirm, but he also offered to meet us where we were staying. The night before the tour,... More

Three had never been to England before and the rest of us only once, so we wanted to see all the most popular sights on this trip. I quickly... More
