Two questions:
We will be renting a car from Sixt for our day trip to the Douro Valley. We would like to make an early start from downtown Porto. I'm wondering whether it would be possible to set the time for the rental to begin in the late afternoon of the previous day, completing all of the necessary paperwork, but to actually pick up the car the next day in order to make an early start and return the car by the same time in the late afternoon.
Can you tell us the status of winery visits at this point in time in light of Covid-19, and are there any other wineries you would recommend for visits besides the ones mentioned in the 10th edition of the Portugal guideboom?
Thanks.
