Just thought I'd add my two pennysworth...
Was lucky enough to fly First with BA last year to Singapre, Sydney, Ayers Rock, Cairns,Melbourne and Fiji - all fabulous places with highlights being Singapore (born there but never been back after 6months old!), Syd and Ayers Rock. Flight excellent, both BA and Qantas (though on Qantas, they tucked my wife in [not me!]) provided outstanding service and cuisine...so much so plan to do it all again next year to take in NZ.
Also been to Florida/Disney 5 times, Caymans, Bahamas, St. Lucia, NY 3 times, Vegas twice, SanFran twice and a fantastic VH tour of West Coast of USA, with add on in Hawaii, Maui. Grand Canyon, Yosemite, Bryce Canyon, SanFran, San Diego all fantastic, but the former 3, awe inspiring, as well as the sunsets in Maui, just disappearing in front of your eyes...magnificent!
Happy Days!!
