Please let us know whether or not Celebrity allows you to board. We are facing the same problem and, after hours on the phone with Celebrity, they advised that we will not be able to board with a visa that has an incorrect point of entry.
We've also submitted a correction request to Vietnam's eVisa support and are waiting for a reply as we were told, also by Celebrity, that we cannot simply reapply for a new eVisa with corrected information if one has already been issued.
Thank you for any insight you are able to provide.
Apologies, my query above was in response to shipmate13's post, now correctly quoted above. I had forgotten to do so initially.
