Renewing your vows are no different than getting married at the parks. No difference in price or options. Maybe the only difference is how big of an event you want to make of it. Other options you can explore is having it at the Dolphin or Swan, both are very good options and usually for a lower price than a Disney owned property.

 

You can still have characters at your event as well. In my opinion if I were to renew my vows this is an option I would seriously explore. I have stayed at the Dolphin 3 times and was never disappointed.
