I see you live in Canada. So both Accounts have to be Canadian Accounts or both have to be USA Accounts. You contact the Wyndham Transfer Office in Orlando Florida. There is a $299 fee. You have to choose which is the surviving Account and which Account will be going away. The Account going away will be frozen at one point during the Process. So before you start the Consolidation Process transfer all the Credits/Points from the Account going away to the surviving Account. There is an Online form on the Worldmark Web Site. This will count as part of the 2X Transfer Limit for the year. But this gives you access to the Credits/Points during the Process (which can take 6 months or more). You can not transfer Guest Certificates or HKC. But they will move later during the Consolidation. If the two Accounts have different Anniversary dates this can delay the Consolidation. They want to make sure you do not get double Credits/Points. So the Transfer could be delayed until after both Accounts get their Credits/Points for the current year.
Some people believe you should keep the 2 Accounts separate - more Bonus Time, more wait lists, etc and possibly more Guest Certificates and HKC. The MF's will be slightly higher with 2 Axcoumts.
