It is always worth it to go testing – If you don’t want to spend £250 a day on the hospitality then go for one of the circuit tours that cost €50 as this gets you entry to the circuit for the day (usually €18 without a tour) and access to all the open grandstands, as well as a tour of the circuit, including the paddock (if your lucky you may see a driver or 2), pit buildings and a drive around the inner circuit roads right next to the cars on track, you can also go onto the roof of the pit buildings and look down on the cars which is great. Book the tour on line at the circuit website as they tend to sell out quite quickly if you do want to go for that option. Last year the Red Bull drivers ventured out into some of the grandstands to sign autographs – you just need to be in the right place at the right time for stuff like that.
