hi, Jomtiened
just walk in ... go to the lift... not need to register........beside that is a restuarant on the 36th Fl and cafe on the 2nd fl ...which u can always pretend that u r heading off for food and drinks...if u get ask........if your friend has a car... just park in the car in the car park...which is connected to the hotel on level one (1st floor... where as the hotel entry is on the ground floor) .... u can easily get a several persons into the hotel that way....
for a great party...
should always book the room for 2 persons... same price as single ... then u can invite ur friend for a free breadfast as well...
cheers Tjhor
