Harriete - Great report, you actually make this route sound like an adventure we would love. We have always opted for the direct flight out of DFW. I have tried to convince Ms. 2Ag's to go through Mexico (we do like Mexico) and I bet after she reads this report she'll do it.
We travel pretty light so it should be even easier.
Glad you are home safe and hope you are enjoying the time with your daughter.
