I was planning to buy the Lisboa card for transportation and museum entrances, but a friend told me that senior citizens (I am 74) get into museums either free or half price, which if true would make the card less useful to me. Is this correct?
Also, I read that it is advisable to buy tickets to Sintra attractions online to avoid long lines at the ticket window. They offer a small discount online for multiple sites, plus a small senior citizen discount. But my guidebook says that the Lisboa card gives discounts to the Sintra sites, but this could mean waiting in line at their ticket booths. So, what is the best way to do this?
