Will be in Portugal on Liberty Day
 

Hi. We're arriving in Portugal April 20, spending the first few days of our trip in Lisbon (and its surrounding towns). We were planning to then head out to Evora on April 25, but just realized it will be a national holiday that day: Liberty Day. We don't want to be stuck wandering around with everything closed, so any suggestions would be appreciated regarding where it would be best for tourists to be during that day (eg: stay in Lisbon area, go to Evora, etc.). Our preliminary plan is to spend a couple of days in Evora, head on to Obidos, and then go north.
