Wonderful guide, BUT ... delay leaving port caused arrival at Stonehenge w/about 30 other buses. 1.2 hour wait in line, no time for visitor center or food. Windsor was great, but completely rushed. Not worth it after first line, then 2nd security line. Chose St. George church over castle apartments. No time to explore Windsor. Had to be back to bus "to avoid London traffic", Then drop off was 2.5 hours. Could have been much better planned. Too much waiting, not worth the cost. Great people with good intentions. Would try again with Int'l Friends but not this tour.
