Bellagio Cirque du Soleiu was amazing 90 mins wizzed by, stunning show. There's three different cirque du soleiu shows in town, just walked past a beatles themed one.
Book the helicopter flight here. use the concierge in you hotel to check prices, They do a 6:30am flight or late afternoon, duration is 2.5-3hours, or you can go by bus for $88 (think pink fancy mini coach that can go off road apparently) but it's a 13hour trip. As we've driven 1400 miles in 8 days we didn't fancy more.
if you pop over to the shopping complexes like the mile, then there are free guide books with a great map of the strip showing where most stuff is, contact details, prices.
I found a Vegas Foto shop opposite ceasars palace, didn't look that great, you might be able to google.
forget the casino's, but check out the hotel free shows. Bellagio has the fountains every 30 mins, caesars forum (shops) end of the second floor has moving statues on the hour 11am-11pm etc. Shop prices seemed pretty good in there as well and they have a great cowboy hat and boot shop/
Flamingos has a flamingo area thats free, mirage has dolphins and tigers but it's not really worth it for the $20. Lots to see for free, lots of places to eat at all budgets. Walk with the missus in the evening and you don't get handfuls of adverts for girls services thrust at you (20 mins to your room!). Venitian is fun, $20 each for a 15 min gondola ride and they sing at you all the way.
cheers.
