Next month my flight arrives at 6 am and the next flight leaves at 8 pm.

I don't really want to leave the airport and I don't want to take a day room at the airport hotel. I don't need to sleep.

My connecting flight is with Flydubai from Terminal 3. I have Gold status so will use the lounge for a shower, and to relax, eat and drink! I may pay extra to use the First Class lounge.

How many hours would I be allowed in the lounge?

Thanks.
