Have dinner at one of the restaurants in the hotel. Take a taxi to the international terminal. Much cheaper than a day room, and will easily kill 5 hours.
Just an update: we tried this, and the Intercontinental spa services
are for hotel guests only. This is also true at the Taj Lands End,
and the concierge there said he's not aware of any hotel in the area
that allows that sort of thing. YMMV.
