Ok since I dont want to change my age at the moment and you seem happy being a baby. Lets leave the room and have fun at the resort you say.
Your baby girlfriend acting like the baby she was now, agreed and clapped her hands.
First off lets go to the pool now I believe there should be a new bathing suit for you.
You look in her luggage and spot a baby girl bathing suit. You dress your baby girlfriend, and then yourself and go to the pool. You place your girlfirend in the kiddie pool where babies and kids swam. Probably some of them also stayed in an age room.
At the pool there was mermaids and other mythical creatures. There were even some animals swimming probably all from animal rooms. Thats when..
