Please help me plan this.
It appears that there are plenty of trains, but the time constraint seems to come in when we attempt to include a guided public walking tour of Cambridge. It appears the tours are at 11:00 and 13:00.
I don't quite see how to do Ely before Cambridge,so I'm thinking that we get to Cambridge in plenty of time to take the two hour walking tour at 11, which would finish up around 13:00. At that point we would take a train to Ely and spend a few hours in a more leisurely fashion.
When done there, we would get a train back to London.
Some sticking points for me are
1) the timing of the Cambridge tour. Could we plan a self-guided tour or would it be too difficult to enter certain places without a guide? Another possibility would be to splurge on a private tour at about 35£ pp. Really a bit too expensive but if there isn't another way.
2) Ely Cathedral opens at 10:00. Maybe we could go straight there from London and get to Cambridge for the 13:00 tour. Seems rushed as I am very fond of cathedrals.
3. How the heck do I book the train tickets once I decide? National Rail site only has return options with no third destination option.
I could really use your help. Thanks.
