So now I'm running into the same ridiculous problem that I know many others have had in the past: Chase will not transfer because the names do not match exactly, but Chase's system will only preserve a middle initial (and not a full middle name).
So what's the easiest solution here? Try to get Hyatt to change the middle name to just a letter (it only shows the initial on the website but I'm assuming they actually have the full middle name in their system) or have both Chase and Hyatt remove the middle name completely?
