Not sure if you're asking whether you should do this or for tactics on getting away with it?
The former has to be up to you but the latter...leave the kid with the parents and surprise her with a spa treatment preferably one that lasts 2-3 hours 5555

The area around emporium shopping center on suk soi 24 might be a good place to pull this off also maybe you can leave her there to do shopping while you "go to the cinema" on the top floor. Buy a ticket and make a swift exit
