I'm looking into staying in Istanbul for one night and considering btwn the Grand Hyatt and the Hyatt Regency.

I will be using points for my stay and the GH is level 4 while RH is level 5 so 3k point difference.

I have a flight at 7:30 am so I will likely check out at say 5'ish.

I will only be in Istanbul for one day so I will likely not be in the hotel that much.

I do plan on using the pool though.

Any thoughts on which one has the better pool/exercise facilities?
