Basically, the key to success in resource management games is mathematics. If the "Play"-button at the beginning of a new level is disabled, you first have to purchase a new building or feature at the shop. They can definitely make the difference whether you can beat a level in expert time or not. Try to never miss the money letters which appear over hotels on a regular basis. When you plan to build only one or two types of hotels train a number of workers according to the number you need to perform certain improvements on those hotels. Order materials before you have less than 500, because it is really annoying if you suddenly have to stop assigning tasks because you are out of materials. Always order the largest amount of materials you can afford to, because the discount is very distinct and you will need a large amount of materials sooner or later. Do not train more workers than necessary in the beginning of any level, because they are really expensive and you can’t use them anyway if you lack money and materials. If you can avoid it never build commercial, service buildings or decorations on lots with income bonus, because this would be just a waste of what could be an easy additional income. Try to purchase every lot with an income bonus if possible, because they do not differ from "ordinary lots" in their sale price, but offer a huge advantage when they are yours. You can see how much it will cost you to restore the building (even if you haven’t purchased it yet) by clicking on that building and hovering over the wrench-button. Take this into consideration from the beginning. In most of those cases you not only have to buy the said building, but also restore it with a high number of workers and a large amount of materials. In some levels you will have to purchase special areas or buildings, which are only available in that level and crucial to finish it. Of course this makes the game less exciting, but otherwise some of the levels are really hard as they are, so it is good to know that there are no additional "bad surprises". In contrast to similar games it never happens that additional goals appear during a level. By holding exhibitions at the Museum you can double the guests of all of your hotels on the resort. The museum can come in very handy if you need a high number of guests.
For one thing you can buy every building whenever you want to, and for another thing you can change the prices of your as well as other buildings up and down. Especially the Real Estate Agency is virtually required to beat some levels in expert time. Service buildings are quite expensive to construct, but they are definitely worth it.By the way, you get new money every 15 seconds. Try to improve your hotels at the beginning of income cycles if possible, because then you lose income as rarely as possible.
Be aware of the fact that you do not get any income from hotels when they get repaired, upgraded or are up for sale.These plots are perfect to build Hotels on that you would sale anyway, because the penalty does not affect the sale price.
Sometimes there are lots with an income penalty of 20%. This strategy has the advantage that you already have a vague plan in your hand and do not waste any time in the beginning. Take your time and think about your first actions, what buildings you will need to beat the level, and then restart the level. It is always a good idea to start any level just to get a general overview related to the goals, which buildings you own, how many empty lots there are, and which buildings are not in your possession in the beginning.
The following strategy guide contains a general tips section, a list of the available buildings and its advantages as well as a walkthrough for each level with screenshots if appropriate.
