According to WalletHub researchers, it generally comes down to cost, convenience and the promise of a memorable experience. To determine the best of the best, analysts compared 182 cities — including the 150 most populated in the United States and at least two of the most populated cities in each state — across three key dimensions: costs; facilities and services; and activities and attractions.

The three dimensions were further evaluated using 27 relevant metrics, including average wedding cost, chapels and churches per capita, number of attractions, florists per capita, and more.
