I’ve been to Montmeló twice. First time in grandstand F, right in front of the breaking zone for the first chicane. Best place for overtaking and run-off’s -especially in the first lap & GP2-. And those cars gearing down… There’s also a large TV screen in front, so you won’t miss a thing. Second time in grandstand G -close to turn 12-. It is great as you can see all the action from turns 10 to 13, and luckly you’ll get some passes at turn 10! The screens are far away though. Pricewise, grandstand F was definitely more expensive than G.
If it’s your first time -or one in a long time- to a GP, I’d go for turn 1. Otherwise, grandstand G offers an unusual stadium-like vision.
