Kirby Cafe Bot / Pokemon / USJ

Hello, I’ll be in Japan in October, and we’re currently looking to make reservations for the Pokémon Café in Ginza and the Kirby Café. Unfortunately, it’s all super complicated. I found a Kirby Café bot on the internet (check Google) that supposedly reserves a table for you when one becomes available.

Has anyone tried this, and does it actually work? Is there something like this for Pokémon as well, or do you have any tips on how to best get a reservation for the Pokémon Café?

Also, I’d like to visit Mario Land at Universal Studios. I’m thinking of booking the Universal Studios ticket that allows you to enter the park 15 minutes early. Will I be able to get into Mario Land quickly without a reservation?

Thanks!
