Which one of these towns should we avoid on Monday due to closings?
Lisbon/Belem
Evora
Tomar
Sintra
What do you want to see in each town.
Is something on your 'must see list' open on a Monday?
If so, make that your "Monday" town
I would say Sintra is the big one to avoid on Monday. A lot of things in Lisbon are closed on Monday so even more people than usual head to Sintra that day. The last time I visited Sintra, my research suggested Thursday as the best day to go. But, I couldn’t see a drop in the number of people even on Thursday.
