This past spring my son and I briefly looked into going. The problem (besides getting tickets to the US games) were two fold.
1. There were almost zero rooms available in Doha. The cheapest when we looked in March was $1000/night. There were some much cheaper options via VRBO type arrangements but they didn't look all above board. I have talked to some guys that got some crazy expensive rooms but then are going to cramp 6-10 guys in there on the floor. Yuk.
So many fans are opting to stay outside Qatar and fly in for games.
2. This option is somewhat doable but you are at the mercy of the airlines.
a. Do you risk flying in several hours before the match and then trying to fly back to wherever right after the match?
b. We looked at the flights and its doable IF they run on time. If you wanted to fly reasonably early and long enough after the matches its was kinda doable but then you'd have some long down time. What do you do in Doha after a game then gets over say at midnight and your flight isn't till noon? Get a hotel? Oh wait that's why you aren't staying there in the first place.
c. The flights aren't that cheap so if you have say 3 matches to go to that's another large expense.
So there was one last option and that was to book a package trip via one of the airlines (Qatar). You can still get a package deal that has RT air from Atlanta. 7 nights in a hotel in Doha. Tickets to the US - Wales, US - England, and one other unspecified match. The cost of that package is $9K. If you wanted to go to all 3 US matches and a fourth unspecified match you got 13 nights hotel all for something like $14K.
Sounds bloody expensive to me.
