I forgot to include these five other doubts.

1) What did you like the most (doing) during your holidays?
2) What did you like the most OF your holidays?
3) I didn't go sightseeing in Paris because it was my third time there
is it also possible "because I had been there for the third time".
4) How did you like Paris? OR What was Paris like?
It was fun OR I had fun in Paris (are they both correct?)
5) What was your journey TO Paris like?

Thank you very much for your help.
