My wife and I are using points/miles for our flights and rental car (One of the perks of being married to someone in sales.
). Paying for the hotel because it was too good of a deal to use points.
I don't think I ever spent more than $350 for a flight to/from Houston (took a dozen of them in a 2 year period from '08 to '10). Seeing the sticker price north of $500 was shocking. Maybe it changed since Continental was bought out by United. Too bad Southwest doesn't fly directly to Houston Hobby yet. I'm sure that would be a better alternative for those having to pay for the flight.
On a bright side, you can get a nice hotel for $80/night AFTER TAX. Kind of offsets the expensive flight a bit if you look at it that way.
I mentioned my opinion of Houston in another thread. It's not the world's greatest city but don't crap on it either. It might be the country's least visually-appealing big city(which I describe in that thread) but it's got a personality and great food, not to mention there's a ton of money in that city...and where there's money, there's a ton of options to spend that money (i.e. golf, shopping, restaurants, nightlife, etc).
