PSA: the $25 airport shuttle in Lisbon is a scam, just take the metro for $2
Landed in Lisbon last spring and the guy at the info desk pointed me to a shuttle that cost $25 and took 50 minutes in traffic. A hostel roommate told me the metro red line gets you downtown in 20 minutes for about $2. I felt like such a sucker. What's the worst tourist trap transport you've paid for?
