Stayed at the Grand Hyatt back in January. DO NOT pay the extra "fee" for lounge access; waste of money. Lots of wood all over the hotel and the rooms are decently furnished. Those B&O TVs are a treat (I don't know why though). Over all good stay, but I ended up paying S$400+ per night and I don't think it was worth that much IMHO. Regardless of where you stay (a hotel with or without windows), enjoy your stay in Singapore.
