"Big Wedding"/ vow renewal

So like a lot of people, my husband and I got married at the courthouse and said "one day we'll have a big wedding". Well we decided to do our big wedding on our 5 year anniversary in about a year and I've started looking online to get started planning it and everyone has different opinions on how to do it. Since we're already married should it be more low key or should I do like we had talked about and make it our big wedding!? I'm asking for y'all's opinions on this and possibly some cute tips that you did at your event! Thanks 😊
