Frequently asked questions

Is this plan still useful in high season?

Yes, but use earlier starts and keep more buffer between key stops.

Should I pre-book everything?

Pre-book only high-demand entries. Keep some flexible slots for adaptation.

How much buffer is enough?

A practical baseline is 20 to 30 minutes per major transfer or queue-prone stop.

Advanced optimization note

If your day includes two high-demand attractions, place them in different time windows (morning and late afternoon) and avoid stacking both around midday.

Bottom line

Consistency beats complexity. Small routines prevent most Lisbon ticket friction.
