Don't worry, everything has been talked about. If you couldn't ask something that has been done before, there would likely be no more threads.
Space tourism is a speciality of mine. Its a gigantic scam and Branson is one of the worst offenders.
I'll put below a few of my objections as you've been very general, and if there is anything you wish to focus on, ask about it.
We have been on the verge of civilian space travel since 1969.

Howard Hughes beat Branson to the punch on this bit of marketing by 40 years.
Just because Branson is the latest lunatic to pretend his cheesey brand will succeed, doesn't mean he will be any more successful. If he was serious, would he have asked Bert Rutan to design his space ship? A guy who builds aircraft the exact opposite way round to everyone else? Propellors at the back, horizontal stabilizer at the front, Rudders on the wings? He might just as well have asked George Lucas for a design.

^ For the record, I have flown one of these myself (yes IRL!)
Nice toy, but not a mode of transport for the masses.

Pinning your hopes on this duo ... I can't even finish. And people laugh at FET!
In 2004 it was reported
Meanwhile, Virgin Atlantic Airways founder Sir Richard Branson launched Virgin Galactic at the Royal Aeronautical Society in London on 27 September, promising the first commercial suborbital space flights early in 2007.
But by 2005 it was reported
Virgin Galactic still has major design decisions to make for the SpaceShipTwo (SS2) suborbital craft, which is planned to enter service in 2008 carrying seven tourists and two pilots.
By 2009 and still no tourists they reported
2010 becomes less and less likely as a date. So how long till 2010 becomes 2011 officially?
And now in 2011
No date has been set for the first commercial flight, although news.com.au reported that the company hopes to start taking tourists into space in 2012.
Emperor's new clothes? It should be noted that the company has taken more than $70 million, of refundable deposits in that time. That's one hell of an interest free loan and at least 8 years of premier marketing for Virgin Atlantic.

He's laughing at you all. Suckers!
