Those are some major life milestones in your family, congrats and glad you get to celebrate in style! I agree the resolution is good, forget about it and enjoy the family trip!

It appears there was a major misunderstanding in your March 4th chat, which caused this whole mess. As a tip for the future, anytime you have something important to take care of: call, don't chat. Unlike the phone agents, the chat agents are chatting with multiple customers simultaneously, and misunderstandings do happen.
