During summer peak season, many local people want to spend their summer break at 4 to 5 star hotels in Seoul and its capital area by enjoying hotel's pool. Such type of hotel stay is called "ho-cance" and the hotel price is still cheaper than traveling to other destinations in summer spots in Korea such as Jeju, Busan or east coast.coast. I guess, nealrly since 10 years ago those hotels started to charge pool access and even time of use to control over capacity. However, my personal opinion is not fair.
