BLUF: Can anyone tell me how to buy tickets online for the Monastery?
The RS Portugal guidebook says that tickets are available online but the website in the book is redirected to https://www.patrimoniocultural.gov.pt/publicacao/mosteiro-dos-jeronimos/ which does not have tickets, or really any info on the monastery.
I know that the Lisbon Card offers free entry but it also seems that you need to stand in the ticket line anyway.
I assumed until now that this would not be a big deal as in my past visit to Lisbon during the off season (do off seasons even exist anymore?) nothing was terribly busy or with long lines. Unfortunately my sister is there today and waited an hour to get in. I am obviously hoping to avoid this when I visit next month.
Any advice?
