Favorite/most used lot type?

My answer is that I like having a blend of the different lots. I do send my sims out to different places and I like to mix it up. I have everything from a nice swimming pool, to a Fitness Stuff themed fitness center, a movie theatre/bowling alley, an ice rink I downloaded, a flowery cafe I downloaded, a library for Newcrest, 8+ restaurants, etc. There's a lot going on and I have a lot of options for where to send sims.

I don't want sims to be too similar to each other so with all the different types of venues, I have more fun. I do have numerous bars and I edited some of them. I redid the bar in Brindleton Bay to be a chowder restaurant. The one in Oasis Springs and the Sgt. Pepper Pub were redecorated. There was a Maxis-made swimming pool that I added to Oasis Springs that is great. I added pools to nearly every gym except the one in San Myshuno.
