Welcome to the forum!
For an elegant atmosphere for your wedding, I would look into the wedding salons at the Wynn, Venetian/Palazzo, Bellagio and Mandalay Bay. I found these hotels to have very modern, elegant salons. Also worth checking out on-line are Caesars Palace and Planet Hollywood. On each hotel's website will be an page for their wedding services. From that page you can request brochures to be sent to you via email as a pdf attachment. I would share mine, but the prices are 2 years outdated! I found that I had the brochure emailed to me within 48 hours of my request.
FH and I decided to get married at the Wynn. The packages fit our tastes and our budget better than any other wedding salon on the Strip. Our wedding coordinators have been an absolute pleasure to work with and have made the planning process a stress-free and enjoyable one.
Good luck with your planning. The girls on the Las Vegas thread are always here to help with any questions you may have
