Any advice for the Grand Prix in Monaco?

Take lots of pics and post them up when you are back .What a cool experience. Have fun

 

Really depends on what sort of trip you have planned...

Budget warrior (<$5K)
Middle of the road ($10-20K)
Decadence (>$50k)

 

As above the tips will depend on exactly what sort of trip you are doing - as an example if you are not staying in Monaco the sensible way in is by train but for a no-expense spared trip you may already have a helicopter or yacht booked - also there's many years of monaco gp trip advice already posted

 

Whatever you think stuff will cost, double it, but most importantly, enjoy it.

 

I've been attending the GP de MC since 1992 (except for a one-year COVID gap), and posted my tips at length many years ago. The advice may be a bit dated, but if you do a search for "Monaco" in this (F-1) sub-forum, a couple of my threads should come up.
If after reading them you have specific questions, reach out to me via PM and I'll do my best to help. Presumably you have race tix and accommodations lined up? If not, this year's race is not an option absent booking a pricey package through one of the tour operators.
It's a fun time- enjoy!

 

There's likely more than one thread, but it's been a while so I don't recall for certain.
In any case, holler if you need help.
