No, it is not necessary to have a highly dense wedding cake if it has a great deal of decorations. Example: The wedding cake can be made as a normal cake; carrot cake, etc., and on the semi-soft icing the baker can put frosting flowers on it, but live flowers are also very popular and do not weight that much. If the decorations are elaborate and fairly weighty then it is the hardness of the icing that will support the decorations.
That depends on their budget.

One of the most important aspects of a wedding is the selection of the wedding cake. It is a fun and enjoyable task for the bride and a moment that all guests await - to admire it as well as to eat it. Although most cakes on display at a wedding do not end up on the plates of the guests (as a sheet of cake secretly await in the kitchen to be served), most guests think that they ate a piece of the masterpiece they saw at the table. However, some couples, especially the ones that celebrate a small wedding, opt for serving the actual wedding cake to their guests. Wedding cakes are like a piece of art, and much care and skill is involved in preparing one. The array of designs, shapes, themes, colors, and techniques are so many that it may be a bit overwhelming to select the perfect wedding cake. Maybe the approach to the task should focus on selecting the wedding cake that is right for the type of wedding, instead. There are many factors to consider when selecting a wedding cake. Besides the beauty and the actual looks, other issues are important. The first thing before committing to a selection is to ask as many questions as possible. This will clear any doubts and any points that might have been fuzzy or left to the imagination during the process. When all items in the list are cleared, the commitment can be made to the baker. Flavor, style, and design are important when selecting a wedding cake. This is something personal for a bride to decide, and the flavors in the cake should be something that the groom and bride enjoy. However, make sure to ask about extra charges for fillings, elaborate decor, and special touches. Inquire about charges for delivery and set up as well. Order the wedding cake in advance; many bakers have a large list and need the orders to be placed six weeks or months ahead to order the necessary components, if they are not on premises. Consider the size of the wedding, the theme, colors, and current season. Tailor your wedding cake to fit those characteristics. Many ingredients in cakes will travel well during the winter, but might not travel as well in the hot summer months. Make sure that your baker is prepared for that. Professional bakers who have been in the business for some time should be aware of that.
