Still deciding...
I've been following this thread for a while since I am going to Hawaii for a couple of weeks. I was excited to see that there was and Executive Level at the hotel. I felt hoodwinked to find out that its only coffee and pastry available. As I'm writing this email I see that they have removed all the descriptions from the Executive Level room Overview, Amenities and In-room Media.
I chatted online with SPG and was able to get the Sheraton Princess Kaiulani for the same rate. The parking is included in the as of April 2016 and you get breakfast for 2.
I'm not sold on either property but leaning toward SPG. I do have until May 30th to cancel one of the reservations.
