We were able to book very early (March) with Iliana for our scouting trip. Iliana was great in replying to e-mails and asking questions in advance that I kind of regret booking the scouting trip so far in advance, and not following up with her before the appointment. Originally we asked for a scouting tour for Garden Chapel at the Flamingo and Silver Sky at the Linq (the Quad / Imperial Palace), but then I added on a suite tour, and then... well, we forgot.
We took a wrong turn and ended up being 5 minutes late to our appointment with Iliana, which didn't matter because she was late, too. The Garden Chapel is very run down and feels like it's stuck in the 90s.
One thing I never realized before getting to the Garden Chapel is that all of their ceremony locations are all right around the wedding chapel. All of the grass is like green astroturf, and the waterfalls are incredibly loud. The gazebo looks just like you see in the photos, but it's plastic flowers around the arch. I was really disappointed, because the Flamingo isn't a steal of a deal, but an example of you get what you pay for. I didn't even bother taking photos.
We then headed back inside the chapel and went with another girl over to the Linq to visit the Silver Sky Chapel. It's in a weird location on the 4th floor; you go up behind a bar by the 3535 bar in this weird little unmarked elevator and follow some weird hallways to find the chapel itself. There's no marking whatsoever, and you're going to want a map for your guests.
The chapel is the same as the photos. It looks like it hasn't aged at all since the remodel in 2010 (back in its Imperial Palace days). No damage to the carpets (other than what you normally see) or to the seats. They did update the mural to include both the High Roller and the new name (the Linq).
They provide you a song list in the package that you can choose from. Your song not there? $25 a song. Replace all 7 songs? It's $75 (definitely a better deal).
