Hi Rose
I too have stayed at Crown Plaza. Very comfortable and convenient with regular shuttle bus24 hrs. Love the Sampans Asian restaurant. Makes an excellent start to the holiday.
Also stayed at Radison Blue. You can walk to terminal from here. Though these can appear expensive, if you keep an eye 'on line,' and you perhaps book in plenty of time, you can sometimes pick up a good deal.
Premier Inn also good, though a little further away, can book a shuttle. Joan.
