Tickets should be about 2k.
$200 for travel assuming you are driving.
Food can vary depending where you eat obviously. If you’re buying 2 quick serve meals in the park it’ll be roughly $40-50/person per day.
I’d guess around $100/person for souvenirs is reasonable for everyone to get a 2-3 things.
Hotel can vary from 200ish a night to $1000/night at Grand Californian.
