ESH. You for being jealous of your sister. Why punish her, she isn't the problem here. It's her day, so be a supportive brother and enjoy her party. Especially after she has spent two years planning this event.

Now onto your parents. They should be more supportive of your desire to hold a bigger party on your own sixteenth birthday. That'd be the more fair outcome in the end. When the party is over bring up the conversation once again. Pushing it now won't solve anything.

Furthermore, don't use a reality show to defend your point. It won't be helpful. Instead begin searching for event halls that might interest you. Perhaps ones that already provide their own activities. Your sister got to plan, why not do it yourself too? You don't need their approval to do that, however; be tactful and maybe a bit mindful of the expense.

Take it from me please. I would've had a sweet sixteen if I hadn't challenged my mother. She had already begun saving money for that event since my birth. Unfortunately I wasn't interested in the idea of having such a massive party. So instead she ended up using that money for things I required. And I still had a pleasant birthday after everything was said and done.
