In regards to a email reply i got from Singapore airport for the specified FINNAIR flights which is on Terminal 1. This also may be useful information if travel now and after, Email reply i got was the following in regards the short term hotel room for transferring:
Terminal 1 Hotel known as Aerotel is operated by Plaza Premium Lounge. As I have explained to you their hotel renovation will complete in September 2015. As you are arriving in January 2016 you still have enough time to book your room with them. You can write to them in September to book a room. Terminal 1 Hotel has more rooms with window view facing the airport runway.
As both your flights are arriving in and departing from Terminal 1, you should ideally book your room in this Terminal without the hassle of transferring from one Terminal to another Terminal without crossing of immigration if your room is booked in another Hotel Terminal.
So i presume i will aventually book a 1 self room as early as posible in October. It seems that i can't do a thing a this stage because with work and construciton going on to this hotel on terminal 1 won't finish till the end of september. So hopefully i get to reserve a room. Just hope it wont be some how fully booked rooms well in advance before i had the chance to do so. After all all i need is a 5 hour room to myself. I get there around 4pm and i depart from there same terminal 1 at 12 at night (midnight) same trip same style like i did preview time.
Just means all i need is some what 5 to 6 hour stay. I must be back to the terminal 1 gates well indeed at least 2 hour before departure. Remember that boarding begins aprox 20minutes before 12 at night. And plane departs at least 15 to 20 minutes later ones everyone is on board.
So in your opinion how will i know how much the rooms will cost when i do it? what does the room looks like ? It all seems renovation and construction but any illustrated pictures for terminal 1 ? And what if all i want was only a 6 hour stay ? maybe now they might not accept that unless yous tay over night or 2. Your opinion to that ?
It is a quite a handy one if you want to refreshes up have a lay down on the bed to rest because you know there is another long haul flight bounce to europe and the lack of sleep on the plane it be imposible.
Finally at the end of the email i got inidicated:
TERMINAL 2 singapore
These 2 Hotels are operated by the Ambassador Transit Hotel.
All Standard Rooms come with ensuite bathroom.
However im not concern about terminal 2 because that isn't my location i be coming nor departing otherwise. But thought i would point this out for these changing planes around in singapore international airport that more then likely your on the FINNAIR
