been to see Christ above Guanabara Bay but I wouldn't call it a wonder.
Petra---OUTSTANDING!!
Giza--twice--going back TY
Just missed Rome by a few hours misconnecting--ended up in LAS for the first time. The only wonder about LAS is why anyone goes there more than once!!
I highly recommend Petra and Jordan is very user friendly.

What about Natural Wonders...??
Good idea for thread Palms
