Mid April, we will be in Sintra two nights, one full day, and we may have some time on our arrival day, but fairly unlikely.
I think I am most interested in the Pena, Monserrate, and Regaleria palaces. I'd love comments on those three as well as the National and Moorish palaces. I'm not sure all three are doable in one day. I'm wondering which palaces people felt were most enjoyable and how much time was spent at each. I think the best strategy would be to start at Pena and then head to Regaleria and Monserrate but I'm open to other suggestions. It does look like Pena is now requiring visitors to reserve day and time for tickets. Thinking it makes sense to book Pena tickets in advance and the other palaces on arrival.
EDITED TO ADD: I just did a forum search and found many comments. I am now considering doing only the gardens of Pena and thinking maybe the end of the day? I do wish the garden ticket still included the terrace. I'd be interested in any more recent comments
Thanks for any and all comments.
