Much had been made of the reluctance of the Welsh, Scottish and Northern Irish associations to give their blessing to the unified GB team.
As it is, no players have been selected from Scotland or Northern Ireland, although five Welshman, including Giggs, have included in the 18-man squad.
"All I have seen [is what is] in the press, really," Giggs said. "As a player and a Welshman, I just wanted to involved.
"Just like the Welsh lads involved, they're Welsh but we just wanted an opportunity to play for Great Britain in an Olympics on home turf so I think it was a chance we couldn't turn down.
"It was one we're excited about and if other people want to disagree with then that's their prerogative, but as a player I am excited and can't wait."
