I have a 5 ½ hour layover in SIN in August on a Saturday (Flight TG 413, arrives 2:30 pm and Flight SG 502, departs 8:05 pm), is this enough time to exit the airport and go to the Hard Rock Café and then make it back to the airport in time for my departure. I’ll already be checked into the Flight 502 with boarding passes in hand. What’s the quickest ways to get Forum Galleria from the airport, and costs, should I hire a car before hand to be there waiting? Any heads up I should be warned about that could throw a wrench into my plans? Of course there is a Hard Rock Café inside the airport, does anyone know if the location name on the glasses differ to what the one in the city has? i.e. Singapore and Singapore Airport? Thanks!
