TASK DEFINITION: Given a travel related situation, and given a specific question about the situation, summarize the question into a title
PROBLEM: Besides the Turkish Lira, can I use US dollars and/or Euros in Istanbul?

I mean particularly for paying in taxis, groceries and vegetable markets.

If this is possible, is there any additional cost for this? I.e. will I pay more if I pay to a taxi driver in US dollars?


SOLUTION: What currencies can I use in Istanbul?

PROBLEM: I am travelling to various destinations in Southeast Asia. What is the best way to go about getting cell + data service? Is there a telecom that offers cheap roaming throughout a broad region, or will I need to get a SIM card in each country I travel to (most of my destinations will be a few days at a time, the most being a week, so this would be a bit inefficient)?


SOLUTION: Cellphone service in Southeast Asia?

PROBLEM: I'm a US citizen and I hold a Washington state Enhanced Driver's License. I'm living in Vancouver for a bit. 

Can I fly domestically without my passport? Micheal Seifert's answer indicates my license will work for the airline, but what about security?

The web says government-issued ID is acceptable for domestic travel, but that obviously presumes Canadian government. 

I get a normal US driver's license probably wouldn't work, but surely if it's good enough for CBS, it's good enough to fly? 


SOLUTION:
Can I fly within Canada with a US EDL?
