Vegas!

Just booked a Vegas getaway for our 10 wedding anniversary!! We haven't been on a vacation, just the 2 of us, since 2008. Both of us have been to Vegas but never together. I went 6 years ago to meet my cousin for her bachelorette party. The Day before I left I got really congested so I was miserable from the plane ride. On top of that my cousin was wild, I felt like I had to "babysit" and keep everyone alive. My husband's Granny took him for his 21st birthday and they just gambled the whole time. To say we are excited is an understatement!! However, I need help with what do while there. Bonus points for the less expensive ideas! Also, no nightclub type stuff because thats totally not us.
