If your goal is to get from your cruise ship to your hotel, door-to-door (nearly), then this is a great service. If you intend to avail yourself of the tour aspect of the service then be prepared to RUN after your tour guide, no sluggards need apply.\n\nAt both Stonehenge and especially Windsor Castle, our guide sprinted between the bus and the attraction. He was out of sight even before the passengers had exited the bus. Sighting him was complicated by the fact that he would remove his International Friends jacket for a non descript blue shirt or swap on a backpack. His "sign" was a blue/black clipboard occasionally held high. If you did not follow, he muttered in particular British humor, "I know I'm missing someone, but I'm going anyway"\n\nHe was knowledgeable about the area, but the bus sound system made him difficult to understand. Otherwise the bus was cool and comfortable.\n\nTrue to the warning on the website, the bus departed only 10 minutes after the scheduled time, leaving 2 passengers at the cruise port.\n\nOverall, some pluses and minuses. Would still use them again after lacing up my trainers.
