We will be staying in Sintra three nights in Mid- March which will allow for two full days to visit sites on a Thursday and Friday. We will book our tickets online 3-4 days before visit dates.
Our plan : Thursday: Sintra National Palace a.m., Monserrate Palace p.m.
Friday: Pena Palace a.m., Quinta da Regaleira p.m.
We will Uber frequently to avoid long uphill walks and for time efficiency (my wife wants to Tuk-Tuk also at least once). How does this schedule look? Should we switch Pena Palace to an afternoon? For Pena Palace we will buy Park and Palace tickets as well as the round trip shuttle bus from the ticket office at the Park entrance. We also will Uber to and from Pena Palace.
Thanks for any help.
