Exclusive Feature: Not every hotel can be perfect, not even yours; internet is sometimes spotty, food is sometimes cold, the block party you booked got a little too rowdy for some guests.

In the hotel industry, anything can happen, and when it does, guests always seem to take notice.

This year was no exception.

A TrustYou study¹ of more than 1 million hotel guest's comments showcases the top hotel raves, and the dreaded rants, that made their stay memorable in 2012.

Here's a breakdown of the report:

Good news/bad news:

There are some key standouts in the comments. The good news is that customers are quick to pay a compliment. The number of positive comments outweighs the numbers of negative. TrustYou said about 81 percent of the reviews they analyzed were positive.

The bad news: the complaints really haven't changed over the years. The top complaints - service, food, dirty rooms, room size and pricing, continue to rank as the most annoying aspects of hotel stays.

The takeaway: 2013 should be the Year of Stellar Service for hotels. The biggest rant of these comments was focused on service, sending a clear signal to hotels -- improve your customer service and win back repeat guests.
