I’ve done it 3 times, 3 very different ways. 1st tent in Blue Nord, it’s literally opposite the entrance by the Ferris wheel, good but quite open and abit loud at times (Dutch love there happy hardcore!), showers and toilets were adequate (no hook up available). 2nd was glancing at Porsche Curves, absolutely amazing experience but pricey, great place to watch, but it’s a lot further to main village than you anticipate. 3rd was a stag do, first time inside circuit, that was probably best experience but watched very little of race. Highlights for me, First evening qualifying, tired from drive down from NW England, stands are quiet so get above the pit Lane and experience the cars and the main straight, Friday parade and subsequent fun in LeMans then tram back to the circuit, absolutely brilliant! Last time we managed to stay up all night and got to the inside of Porsche Curves for sun rise clutching a box of red wine and napping on the banking, if you can manage it, do it, then get head down for a couple of hours then back to track for the last few hours. Drive home isn’t much fun, be careful of hidden speed cameras and the french police trying to relieve you of your euro’s.
Having said all the above, I’m waiting for 2023 for the new regs before I return, plan on doing the Nurburgring 24 hours instead next year, that looks epic too.
