Lisbon/Cascais
 

We are planning a trip end of August - we would like to stay in Lisbon for 4 days and also visit Cascais for 2 days before moving on from that area. My question is - is it worth getting a second hotel for the 2 days in Cascais or should we just commute from Lisbon since it's so close! I'm just trying to weigh the hassle of moving versus getting a better feel for the city by making the move. Thanks.

Caiscais is very near Lisbon. We spent a day out there and in adjacent Estoril, traveled by train I think. For only two days I would stay put in Lisbon.
