but I'm concerned by the lack of personal contact between seats!
You want to be concerned at the price more than anything mate!!!
However, It is very nice and extremely comfy!! i was lucky enough to travel to orlando in virgins upperclass suite on the top deck of the 747. There is relevant space for two as there is a seat tht is constructed at one end, if you look on the website it will tell you about it. There is one down side to the whole experience, the cost, extremely expensive, one has to ask ones self if 5K return to the states per person is worth it!! nevermind paying for the rest of the holiday!
Your choice mate.
