Hi, I am looking to take my explorers section to London for a day in March and while planning travel I came across the Group Day Travelcard (paper). We plan to be a joint group of about 18 to begin with and then split off at some point. Some of the groups may be a mix of both over 16s and under 16s. Will we have to pay for a 16+ group ticket anyway? And, is there a limit on the group size? The TfL site just says ten or more.
Thanks
