I am using SC Party Makers for my wedding at the Ole Hanson Beach Club.\r
They have the best prices in the area on all rentals. Plus, their website offers a 10% off, just for mentioning the add. The only items that they will not discount are linens, so you might want to try another company for that.\r
Overall, they get back to you in a timely manner. They are very easy to work with. Plus they have another office in Newport Beach if you can't find what you are looking for in San Clemente.
