Grand Prix tickets

[HMSSophia]

My DM is a F1 fan. I am not. However before she gets too old I think she'd love a day at a Formula 1 Grand Prix.

Silverstone appear to only offer three days (no! I can stand one day but not three!).

Am I correct?

Where is a good place to be? Anywhere to avoid? Any hints tips?

Monaco you can do single days, including the Thursday practice day.

Very expensive though.

I haven’t looked for next year, but you can usually purchase tickets separately for each of the 3 days at Silverstone, unless they’re sold out already? We went on the Saturday this year.

I'm not taking her to Monaco!!

Ok so one can do 1 day at silverstone that's good. Are ticket sellers like Viagogo (?) ok to buy from?
