Wow, I feel like an oblivious American right about now.
It has never occurred to me that people are denied visa's for reasons other than criminal background, or that you can't call anywhere in the world except maybe North Korea, etc.
I'm so sorry you can't go with your husband on his trip, follow through on your plans, etc.
I think I'd enjoy Thailand. I love a good swim.
Have a wonderful and relaxing trip.
