For lots of sinless fun in Las Vegas, these are my favorite options:
Take a trip to the top of Eiffel Tower at the Paris Las Vegas Hotel – nighttime is best for a view of the dancing fountains at the Bellagio.
Zip to the top of the Stratosphere Hotel Tower for moonlight photo ops and terror-inducing rides.
Fabulous Italian food can be found at Liberace’s Carluccio’s Tivoli Gardens – the pizza, pasta and ambience are delicious and made for sharing [editor's note: now closed]. Tour the Liberace Museum located in the same shopping plaza on Tropicana Ave. before you dine.
A visit to Ethel M’s Chocolate Factory and Botanical Cactus Garden in Henderson is a sweet treat; the candy factory tour is free, and the botanical garden is spectacular.
One of the tastiest (not to mention vegetarian-friendly) buffets in Las Vegas is inside the downtown Main Street Station Casino.
For pleasant, reasonably priced off-strip accommodations, choose the Silverton Casino Hotel, sporting large indoor fish aquariums, or the Emerald Suites, featuring full kitchens and double master bedrooms. No sin required.
