Awwwe thank you LoneyBones, its for sure she would have loved to go to Vagas.
As to your other offer, One place my sister has always wanted to go was to a New Years day concert at Musikverein in Vienna. She watches it on TV every year and has always dreamed of going there. She would love to see herself there.
Famous people, well mostly music is her life these days and if she were be in the company of someone famous she would probably like them to sing or perform for her! Her favourite all time singer is Nana Mouskouri ( favourite song - Song for Liberty.. just so you can capture her spirit)

She would love to see her perform, - wonder if thats at all possible, putting Nanna Mouskouri at Musikverein with my sister there to....
