Emirates Skywards - Long layover in DXB

I'll be spending a good 7 hours from midnight on a Friday in the middle of the summer in DXB(2 different tickets so no STPC provided). And don't want to stay in the airport hotel nor go landside. I'm only getting access to the old J lounge as my onward flight is in Y.

Do you reckon the J lounge will be sufficient to catch a nap, or should I upgrade to J and suffer at the noisy J lounge in T3, or should I just book a hotel and go on a later flight?

I am also thinking of catching a 3AM flight on a different airline.

Book a later flight and go rest up at LE meridian - that's the STPC hotel EK uses for F pax but this time of year you can get a room very cheap and it's a great place to relax (nice room, pool, restaurants and 10 min max from the terminal
