I agree that Gold's Gym has some very strange ideas about when people want to work out. If location is your main consideration then I would recommend Al Massa (Ramada Signal) ... They are about the same price annually as Gold's but open 6am - 11pm (dedicated male and female side's to the gym) All the hotel gyms (with the exception of Sheraton, Intercontinental) are relatively small and ill equipped and pricey as well. The only other cheaper option would be to check out the Aspire gym (park next to Villagio and walk towards the Dome and ask security where the gym is) I cant confirm this myself but have heard that they only charge 150 per month (and free for locals) but this is hearsay on my part. Good luck
