So, For as many issues as I have with my FMIL, I adore my FFIL. He has his quirks, but he's pretty awesome.
Friday night, FI and I had our company Christmas party at a pretty swanky hotel here in town. It's a very beautiful old hotel that was built when the city was built around the time of the oil booms. Beautiful deco buildings. Just lovely. The whole night FI and I kept saying that we wished we could afford to have the reception there. It was just so pretty.
So as we're leaving, FI tells me to pull over into a Quik Trip (a local ((amazing)) gas station). He says "So I have this." and starts unfolding a piece of paper and hands it to me. The paper was confirmation for reservations for that hotel for the 3 days following our wedding.
FFIL feels bad that FI and I can't afford to go anywhere for our honeymoon or afford to take off time for it. He and FMIL had the same kind of deal and it took them 30 years to take their honeymoon, so he said that if we can't go anywhere, he at least wants us to stay in the best place in town. He sprung for all the extras, including valet parking, champagne and strawberries, penthouse suite, the works.
It still hasn't sunk in that he did that for us, but it was just too sweet. I'm still kinda at a loss. 
He may be Ex-Air Force, but he is a big softie when it comes to his family.
