i have been to the that hotel, and i must say it is a great hotel but it doesnt have a lounge.
i found the Westin Nusa Dua Bali better.
the suites for Platinum upgrades are really nice. modern, new and stylish.
westin nusa dua bali has larger suites, but they are not that modern .
i think i have pictures of both hotels somewere, if you need , i can email you the photoalbum i did create that time. just pm me.
if you need help on the westin nusa dua, you might try to ask DIANA, who is the master of the NUSA Dua

and the loved baby of the RBC lounge staff.
i have know some persons on both hotels too, so if you need email adresses you can pm me too.
