5. The reception
You will need to decide what kind of reception you want to have. Will it be held at a nearby restaurant or hall? If so, they may not be too keen on having sand from the beach tracked into their premises. You will have to ensure there are facilities for you and your guests to clean up.
Will it be held in a pavilion on the beach? This may be easier, more fun and cheaper, but you will need to make sure it is covered by your permit and coordinate with your caterer and vendors. Alternatively, you could choose to leave it to the professionals. This option may be a little more costly, but will generally be a lot less stressful.
