Its a pity about the Radison...it has now been totally renovated and has been taken over by Sebel..It looks terrific..its across the road from Manly Beach in an absolutely wonderful position with the best views.(totally relaxing)
I have not seen the pool renovation..it used to have a very ordinary small pool,but do you really need one, with the beach opposite and also the Bower sea pool is just a five minutes walk along stunning path to Shelley Beach. Shelley Beach is also very calm and sheltered if you dont like waves.(I highly recommend this hotel for its position and beachside resort.
Crowne Plaza Coogee Beach is in a nice position..(not on beach)and is a lovely beach..but you wont have the pleasure of travelling on Sydney ferries across stunning Sydney Harbour to get to your destinations, like Manly.
Four Seasons is in a fab position..if you want city accommadation. The pool I have not seen..go onto their website and checkout their facilities..usually always have pictures of swimming pools.
To narrow it down for you..
Radisson Manly..even if you only have South Tower
Four Seasons in the city.
Manly Pacific is opposite beach but personally having stayed at both I would choose the new Sebel.
Park Hyatt has a lovely swimming pool overlooking Harbour Bridge but it certainly has a price tag to go with it.
Star City - has a large outside swimming pool.
Probably have totally confused you now!!
My pick is the new Sebel.
