I've been following F1 for 50 yrs....
I went to Montreal F1 once, in '97s. I liked it and Montreal was maybe the easiest and cheapest to see, only $ 140 for 3 days. Plus hotel etc.
I found out why so cheap - I sat among Quebec Nationalists waving their blue/white flags...
Wasn't a problem for me and they offered excellent chicken and wine and we party together.
Last year I wanted to go to Las Vegas but the cheapest package was $ 1500! Crazy...
It's big circus with high ticket prices and hard to see anything more than 30 sec per lap.
Now I see it on Sky F1 at home, or where ever I am, via VPN. Suits me best and moust relaxed.
But be there at least once is great! Better not to plan anything, just go with the flow.
