In Vegas, you are always going to get a little lost in a casino. So yeah, you're going to ask for directions from time to time.
Only once have I been to Stratosphere. Upon entry, I had no idea where I was going and was supposed to meet with my friends who were staying there in the hotel. I asked for directions, and the response I got from a woman who worked there was less than friendly. She basically said, "Just read the signs!" and pointed to them in a very rude way. I was stunned at her lack of customer service skills. My first thought, "Thanks for trying to make me feel like an idiot."
Very bad FIRST IMPRESSION.
Room serice was awesome though. 24/7 room service available...got waffles at 3 am. They weren't too bad, either.
