We are trying to see the following sites.
1. Pena palace (930-7)
2. Moorish castle (930-8)
3. Quinta de Regaleria (10-8PM)
4. National palace (930-7PM)
5. Monserrate palace (930-7)
It's a little ambitious obviously and we might have to drop #4 or #5. However, we don't mind taking taxis as it'll likely help a lot.
I was thinking of being at Pena Palace at 930 and visit Pena and then Moorish castle. Figure we'd be done visiting Moorish castle by noon, take a taxi to national palace and visit. Grab lunch around 130-2 or so. Then take a taxi to Quinta de Regaleria and another taxi to Monserrate. It'll make for a full day. Probably be done closer 6-7PM. Then a taxi back to Lisbon.
Is this do-able with the help of the taxis?
