So much potential, but not there yet
I attended a conference at the El Tropicano last week and was so disappointed. The hotel is beautiful and the decor is fun, but they're missing the mark in so many areas. Probably the worst problem was that it was absolutely impossible to get a stable internet connection anywhere in the hotel. For business travelers who need to connect with clients via e-mail and web applications, this is a major problem. 
Other issues-- my room was over the carport in front of the hotel and I could hear the tropical music all night long, even with the balcony door closed. Not so irritating at 6:00 p.m., but at 3:00 in the morning, it's a huge problem. Cars had to be valet parked, which is fine, except that at 6:30 at night, nobody was in the valet booth to get my car. Likewise at 9:00 p.m. when we returned there was also nobody available to take the car, and my traveling companion had to ask the front desk to take care of it. 
There is an onsite restaurant advertised, however it only serves a mediocre buffet breakfast (the same type that would be free at a Hampton Inn type property). While there are hours posted for lunch and dinner, the restaurant is actually closed and the only food available on the property are pre-prepared deli sandwiches and salads at the coffee bar in the lobby. Since there are very few restaurants within walking distance, this is another big problem, especially during a busy conference. 
The bathroom had dark brown wallpaper which was cute, but also showed every water droplet and dust particle. It made the bathroom look dirtier than it probably was. Rooms have individual air conditioning units, however mine either blew so hard that I was frozen or was off. 
All in all, I was so disappointed in the El Tropicano. The decor is cute, most of the staff is friendly, but the basics that I'd expect for a business traveler are absolutely not in place.
