Hi nasher,
Haven't even found the suitcases yet, let alone packed them !! There's still five days to go, so there's no cause for panic yet.
With regard to the lager, the two main Portuguese ones available are Sagres ( believe it or not, my favourite ) and Superbock, although you can also get Cristal and Tagus as well. In the main resorts such as Albufeira, all the English brands are available and I've read somewhere that one of the lagers available on A/I in the Paraiso is Fosters.
I take it you've read linsta's post regarding the deposit situation - that's good news
Will let you have my report on the hotel on my return; have a good Christmas.
