Hi! My sister with her son(age 10) and I (we are from the Philippines),

we are planning to go to Shanghai Disneyland. We will be meeting my older sister and her husband & daughter there coming from USA. I will be bringing my son too (age 6). My question is that, is there a chance the kids can have an approved visas? Although we will be attaching our itinerary including round trip air ticket booking record and proof of hotel reservation once we apply for our Chinese entry permits. We will be staying there for 3 days only. Is there a travel agency who can process our application?
