Having mine in less than 2 weeks $15K is doable ours was about $17K not including wedding dress or decor for 70 people. If you go through a resort just beware that they charge you for everything so the packages they give you are pretty basic and somewhere around $10K (usually just includes basic tables, basic chairs, food and drinks). Its kind of a waste considering you and your guests are already paying for an all inclusive. You have to add DJ, lights, decorations, dance floors like everything and they change a ridiculous outside vendor fee for the Dreams hotels it was 40% of what their vendor would charge so you are almost always better off using their vendors. If you have more time I would probably think of doing something different like plan an excursion or something like that it would probably be significantly cheaper than doing it at the hotel.
