Is better SEO to have one website with different locations hotels or a web for each?

I took the leadership in a group of hotels and I don't know if for SEO is better to have one web where it has all the locations so it has a lot of users going in and different pages specify different Key Word of that location; or different websites for each location so it has each less users but a bigger percentage of the entire website specifies more in the Key Word of the location name.

We speak Spanish in this forum

The better option is different website for different locations, the best advantage that you can use a specifics keywords for each hotel.
