How much is the taxi ride from the airport to your hotel? How much is your airport shuttle service?
I took uber from the airport last month, and the price was 56,000 dong with the airport fee included (10k dong). That is less than $3. The hotel called the taxi for me on the way back to the airport and it was still less than $5. Make sure to NOT get the SUV taxi from the hotel and get a regular size car, the fare was almost twice as high when going downtown.
