Our flight arrives at 8 p.m. at LIsbon Airport (May 2013). We understand the shuttle bus no longer runs to Cascais and wonder if we will be too late for the 91 bus to Cais do Sodre station so that we can then get a train to Cascais. If we will be too late, is there an alternative? There are only two of us and it would not be worthwhile getting a taxi for the whole journey from the airport to Cascais. Many thanks in advance for any advice.
