hi, I am arriving in singapore at midnight and staying at the airport hotel at terminal 1. I have a connecting singapore flight at 1:10pm. I will leave the airport around 7:30am and go to Marina bay gardens for a couple of hours.

Question i have, where do i store my carry on luggage at the airport. do i have to go to terminal 2 departures and store it there. (My singapore airlines flight departs from there), then when i come back from marina bay gardens i go pick it up from there? or should i store it when i exit terminal 1 and leave it at the storage lockers that the airport provides?

Thanks
