"Cases doesn't mean they are not reliable". Still not worth to take the risk.

With AirAsiaGo, you may face the risk of they did not answer your call when anything happened. If you book directly with hotel, you found some problem when you arrived at the hotel, and you show your receipt, at least the staff there will do something (e.g. accommodate you to another hotel free of charge). If you book through AirAsiaGo, the printed receipt only can proof that you book the hotel with AirAsiaGo, it cannot proof that AirAsiaGo send your booking to the hotel. When anything happened, and AirAsiaGo do not answer your call, you will understand why I say all these.

However, I am just here to give advice. Follow or not, it is up to you. If anyone still want to use AirAsiaGo / AirAsia GoHoliday, go ahead. But, when anything happened, don't blame me for not giving advice.

However, if anyone still want to use AirAsiaGo / GoHoliday to make hotel booking, my other advice: After your booking, call the hotel to confirm that they receive your booking.
