Mandalay Bay has these great big bathtubs that are begging to be overflowing with bubbles and Lush delivers (well they don't actually deliver-but that would be cool if they did provide room service to bring you some soap lol). My room had a jetted jacuzzi tub. I came to Lush and bought 2 Sunny Side bubble bath bars. It smelled like citrus and was covered in shimmery gold dust that makes your water glitter (the French Kiss bubble bath bar is also very yummy and smells like lavender and turns your water purple)! I broke off half of one of these bad boys and crumpled it into the warm water while the jets were on, and sure enough within 5 minutes there were bubbles everywhere- EVERYWHERE. It was faaaaaaaaaaaaaaantastic, and I ended up with some glitter on me too :).
