If you are a movie buff or you just get a sudden urge of watching movie, you can head to movie theater and its absolutely free.
If you are tired of a long flight and looking for a nice massage or any other spa/salon treatment you have a choices of spas to choose. You can also rent a room on hours basis and take a nap before your next flight. You also have a option to just rent a shower and feel fresh before your next flight. I didn't go for any spa treatment but I had a quick peek on a price list and actually prices are pretty reasonable.
If you are on a budget trip, you can enjoy free massage here without shelling out a dime. There are few foot massage chairs, you just need to sit and relax. After walking around, checking out terminal 2, I was exhausted and this free foot massage chairs just worked a charm on my feet.
Personal hygiene Tip- Carry a pair of socks.
Is there is anyone who would say no to shopping? atleast window shopping? Changi airport has plenty to offer for shopaholics like me.
By the time I finished wandering in terminal 2, it was time for my boarding. I wanted to check terminal 1 and 3 as well, but time became my enemy.
Before heading to the boarding, I visited a toilet. Even toilet visit was also a memorable here :)
By the time I started walking towards my boarding, I started wishing secretly for a flight delay, so I can check out other terminals. There was no flight delay and I am sure my itchy feet will definitely make me land in Changi airport once again :)
