We will be visiting Cambridge on a daytrip from London in mid-April. This will be our first time there, but I am certain it will not be the last. We will have only a few hours (arriving 11 am and departing 15:50), so I am thinking we will have lunch at the Eagle pub of Watson and Crick fame, and then a 1:00 walking tour. I see 3 possible choices, all taking 90 minutes and visiting similar sites, so it comes down to, in my view, the best, most interesting guides. So I would like to hear opinions about these:
Small-group tour by 2 “Green Badge slides” who refer to them selves as “Town and Gown” :

Tours offered by Cambridge students and alumni:
https://cambridgealumnitours.co.uk/tours/shared-walking/
And now I cannot find the link for the third option I saw. They offered a choice of several interest-based tours, including a “Science” tour which would be of great interest, although it is not currently on the schedule. The guides are Blue Badge guides; I do remember that, and I thought they met at the Tourist Information Center.
Question: what is the difference between Blue Badge and Green Badge guides?
So, if you have advice for us about which walking tour to choose, I would love to hear it. Thanks!
