I have booked to Bora Bora for my honeymoon from April 4th to April 11th 2012 ( which is also Easter weekend )

i have used my intercontinental reward points to book the following ;
+++++++++++++++++++++++++++++++
4th to 6th april 30,000 points + $60 a night - 2 bedroom family coral suite

6th to 8th april i have used my Ambassador BOGO Certificate paying $1000 for the 6th in an Emerald Over Water Bungalow . The 2nd night is free with my certificate.

8th to 11th april 30,000 points + $60 a night - - 2 bedroom family coral suite
+++++++++++++++++++++++++++++++
its my honeymoon and its easter (busy?) . should i pay the $200 a night for a guaranteed upgrade on the 5 reward nights or assume that there is next to no chance they will move me between the 2 ???? I am a Platinum Ambassador (not Royal )

from the 6th to 8th i should be upgraded to Sapphire OWB - I was wondering about saying to the hotel that i am happy just to take an Emerald for the week as long as its guaranteed for the 5 reward nights....

THOUGHTS ??!!
