Thank you everybody for your warm concern na..esp P'Susan for contacting K.Noinah and for serveral pi pi who've emailed me ka.
I've decided to be a mommy and reminded myself that I am not a young adventurous traveler anymore; so instead of sleeping on the chairs at the terminal, I've checked in to the nap and shower service provided by the airport. I have my own small private bedroom with toilet and shower and there's also free internet and free breakfast at the lounge area. So big tummy and I will be ok for tonight ja.
It costs the same as a American typical hotel (US$119) to stay from 11pm to 7am ... not cheap but I am willing to pay for this than to US$316 airport hotel.
