I own Westin Flex 37,000 StarOptions and Sheraton Flex 67,100 StarOptions. I am wondering if I can combine the two for a total of 104,100 options within Interval International to make trades? For example, If I use 51,700 StarOptions from the Sheraton Flex for 2027 which will give me 15,400 remaining. Can I combine them with the Westin 37,000 and make another reservation for 51,700 for 2027 and Bank the remaining 700 for 2028? Is there any limitations like you have to wait for 8 months out in Interval? I understand that if I keep any remaining Options in Vistana, they can be combined for usage at 8 months.
