My mate has dropped out so I am going stag now. Looks like they are using the Monchique Resort and Spa again which is a nice place with 1 bed apartment setups (have an ensuite master bedroom and a king size sofa bed in the living room with separate bathroom so no sleeping 1m away from a snoring tired track rider
).
Only issue for those after a nightlife is it is 30 mins drive inland from Portimao itself. But only 15-20 mins drive to the track. They have a decent Italian restaurant there.
If anyone is travelling by themselves, if you want someone you have a slight link to, I'm happy to put my name down to share an apartment.
