It's better booking the ticket because of the largest number of people. It's a very nice church. You can buy a cumulative ticket to visit Sagrada Familia, Park Guell and Casa Batlò to save money

We were there at the beginning of July 2019 and I did not even notice that something is closed. I was amazed by that architecture. Totally worth to visit.

Se pretende ficar 3 dias dá até para ir de Comboio até Aveiro, ou Guimarães. Alguns passeios saem do Porto, mas caso não queira gastar dá para ir e voltar no mesmo dia só compre as passagens antes E chegue com 30 min antes para observar seu vagão.Isso evita entrar em lugar errado. Aveiro é muito legal. É uma experiência diferente usar uma embarcação para andar trafegar por algumas de suas rua.Guimarães, tudo a pé Castelo, Mosteiro, Pça da Republica, (1dia)

I am not sure you would have to check with them. Sorry

We just walked up to the cathedral. Line wasn’t bad at all. You only pay if you want to see More than the main sanctuary.

It really depends on you.. but I guess an hour would be just fine.

hi.. i do not know the time table of the missa

Hello, I don't know if you still need the answer, but neither Porto nor Lisbon are easy cities for people with reduced mobility. You would need to take a taxi to go almost everywhere. Taxis are not very expensive, and distances are not so big, but walking there isn't easy, because streets are pretty steep. The Cathedral is also located in an uneasy place to reach on foot for a person with reduced mobility.
