Columbo loung

Departing Male afternoon flight
Arriving Columbo 630 evening
Departing Columbo for Dubai 3 am

Question - Emirates lounge Columbo has staggered open hours ie morning, then late afternoon to 815 and open again 1155 pm

Can one access lounge on business unti l it closes at 815 and return again at 1155 am...better options available? Is lounge open 24 hours? Tried researching this online but not much available that I was able to find.

Thank you
