Once you get past the learning curve, it's very easy to use and move quickly through the program. It is a great program for all aspects of managing hotel be it inventory and rate management, guest management, reservations, sales, accounting. I'm sure in 7 years I've used it, I didn't get to use every function since there was just so much.
What I liked most was that it is quick and easy to access a lot of information (guest, company, or group info or history / room availability and pricing / accounting and sales figures). This was very helpful since easy flow of information is vital to a hotel running smoothly.
When loading rates, I particularly liked that I could set automatic rate adjustments base on parameters such as dates, day of the week, occupancy, room type, or a combination of any of the aforementioned. This automation meant that if sudden inventory changes occurred on the rare occasion that I was not working, the rates would increase or decrease to achieve the best average daily rate and occupancy.
Managing inventory was very easy with Maestro. Even with 9 different room types, I could use various reports to see overall occupancy, occupancy by room types, and also by specific rooms.
I could go on. It is a very solid PMS program and I would use it again.
The only real dislike that I had with this program was the learning curve. Because the particular Maestro PMS we used was easier to use without using a computer mouse, it was essential to learn the mnemonics (ALT- letter combo) of every function. I still remember that to get to reservations was ALT-I-R. This was was complicated by the fact that sometimes the ALT-letter combo varied between different tasks even though they were similar tasks. The best way to explain is an example: In a guest reservation, to access notes I would key in ALT-I-N, in a group reservation, I would have to key in ALT-I-T.
