I have an "interesting" issue I just discovered.
I booked 4 nights (2x2) using personal and business accounts coming up in May. Two different emails and two CC numbers.
initially everything was fine - each reservation sat in its own account.
I just logged in and found that one of the accounts now showing _both_ reservations. The second account still shows only one.
I cannot open the reservation that shows up in both accounts from either of them, getting an error:
Unfortunately reservation xxxxxx does not match your Club Carlson profile and cannot be viewed or modified.

I am wondering if overzealous stuff at hotel somehow "fixed" the issue for me? I contacted them about some other services, to which they never actually replied with useful info, but they did mention that they see 4-night stay.

I havent been charged more points than at original charge, no cancellations were received.

Is it worth:
contacting CC to figure out what is wrong? I am very uneasy about doing it.
contacting hotel? most likely they wont do anything.
leaving it as is? risking that I will have issues when I arrive
cancelling the duplicated reservation and booking a new one? same thing could happen again.

any suggestions?
