We did one of the longer cruises on the Pearl last month and I can say we took advantage of the 2 for 1 Specialty Restaurant promotions. The first week, 2 for 1 were only between 8 - 9 pm in the La Cucina, Mambo's and Lotus Garden. Then the last two weeks was 2 for 1 between 5 - 10 pm in all Specialty Restaurants what a deal, we were able to try almost all of them and some more than once, they were all good. The two main dining rooms are the Summer Palace was very nice but I found it to be a wee bit noisy for me and the Indigo is also nice and more on the quiet side. We didn't have to wait at any of the restaurants. On the shorter cruise I don't think they will offer as much 2 for 1 as we had, check the Freestyle Daily it will tell when the 2 for 1 deals are. You should enjoy the Pearl it is a very nice ship.
