I knew it was madness even to drive TO Sintra. But the hotel was very helpful in trying to help me manage the downsides of coming by car. They advised I park the car immediately and use Ubers, taxis, or TukTuk to get around locally. Check! They had awkward, but OK off-site parking in an enclosed lot a few minutes walk from the hotel. Not great! The keypad activated door closed with us inside the lot. One [70+] person had to climb over the enclosure wall to let the others out! [No keypad inside the lot!! Bad!!] Then later trying to return to the hotel by car to pick up luggage was a horror! Though only a 5-minute walk from lot to hotel, it was almost a 20-minute drive on insane one-way systems back. The hotel itself was delightful. Staff very helpful. Location very convenient. If only we hadn't had a car!
