I'll be coming back to the airport in the early morning hours (flight to NRT @ 7am) and hotel is near the dhoby ghaut mtr. What should I expect to pay for the trip to Changi? I assume there are no shuttles or public buses at that hour. Last time I stayed out near the airport (Joo Chiat road) and was pleasantly surprised by the low fare back to the airport. My hotel told me $35 and I think I paid $17. Had a really nice driver, to boot.
