This is exactly what you would expect. I switched my flight to Saigon a day earlier so I could be there in the morning the following day for a round of golf rather than fly in the following day at noon and loaf in my hotel.
Only problem, I had booked my hotel in the city center for the following day on and couldn’t get the reservation for a night earlier. Enter Ibis by the airport. I landed at midnight, walked across the street from the airport, and crashed out harddddd. For the price it was super nice. Clean, convenient, and functional.
Be warned, I did almost nothing other than check in, shower, and sleep. But for all of those things for that price, it was excellent. It comfortably facilitated my plans and everything was smooth. If you’re looking for more out of an airport hotel, you’re staying in the wrong place (though that’s not to say it wouldn’t deliver –I just don’t know).
