MotoGP Estoril- Anyone been?

[tomo1]

As title, has anyone been to Estoril for any sort of racing in the past? I'm going to my girlfriend's home in Lisbon over the easter/royal wedding break which coincides with the Moto GP race, so my girlfriend suggested we go, but I'm trying to work out where it will be good to watch from... any suggestions would be great, I've only stopped in to have a nosey during a trackday there previously, so don't know what it is like for a spectator, and general admission only gives space between t2-t3-t4 so doesn't look like we will be able to wonder around to find a good spot.

Any advice welcome!!

Cheers,
Jonty
