This would not be an official new land but how about a small area called "Benchland". Maybe over on the old Motorboat Cruise dock they could put a collection of the themed benches from all over the park? Maybe even dig up or re-create some of the old ones from decades back? I'd even add some of the different trash can themes from over the years.
Would be cheap to do, and it would be a happy place for young and old to rest a spell.
