Made my flight, 10 hours to get from LAX to London. I was glad I had business class. First Class had these pod type seats that folded out into mini-beds, I peeked in and tried not to stare. They get food and alcohol out fast to prep passengers for sleep. My seat was like a recliner, much better than regular class but I still had trouble sleeping.
The hotel is extremely modern. I expected some type of traditional hotel but everything is quite modern. My room is small but very clean and efficient. They have a great fridge and coffee pot. I forgot to put out the "Do not disturb" sign the first night and I payed with very loud knocking from the maid (8AM London time, too early!)
I also took the touristy Big Bus tour and got the overview of London. I was ready to fall asleep and moved to the bottom (and warmer) part of the bus and stuck it out to try and acclimate to the time change.
My biggest problem was figuring out how to use the cell phone, dial 011 before the area code etc. I called the hotel operator to ask and she acted like I was a retard for not knowing.... I guess I was.
