Well, after a lot of this during the three weeks past the System merge date, everything went very smoothly for me for some weeks until today.
Yesterday I was able to book some reservations and to finally merge my accounts: all Points, this years nights and Lifetime yxears + nights merged nicely, Lifetime Gold realized and just a few nights to go to LTP, 5 Hours ago I was able to select the 50 nights gift, 3 Hours ago my 5 SNAs had posted...
….and exactly since then - I want to use them for a stay starting next Sunday - I am too getting the error *sigh*
So let's hope htey'll fix it soon and as anooying as it is - and was for the three weeks after the Merger - this is a big Task and I have to say kudos to them for making it happen. In the big Picture, I'm quite happy.
