Am i right or wrong?

So i got this amazing offer from a friend. To move in with her (from FL to VA) so she is coming for the weekend to pick me up. (June 5th-7th) and help me move into her apartment. She also offered to take me to disney on her.

She has a baby almost a year old, and her boyfriend. They also are bringing my boyfriend to help. So, me, my friend (K), her boyfriend (S), and my boyfriend (D) will all be at disney on K and S. All tickets and hotel paid for. (not yet but will be) i kindly told them no, as i am terrified of Mascots and dont like roller coasters. I have a full on panic attack while in the same place as a mascot. They kept trying to change my mind, but i told them no, i will not be fun to have there and for them to have fun then pick me up after the day. I simply will not be able to go to disney. Then she tried saying "if you dont want to go on coasters thats fine, then i need someone to watch *childs name* while we go ride. So i told her, i can not go to disney, i will have a panic attack. She then asks me to babysit at a hotel. (i do not drive yet, so we will be stuck in the room all day) i told her, (to be nice) that i didnt have an issue with it. But am i wrong to be annoyed that she wants me to babysit while they are at disney? I offered for us to do something else but she didnt want to do that.

Also when i move in, is it wrong for me to not like it when their family just randomly comes into the house? Yea my name will be on the lease, and i will be splitting bills. Their family does not live with us. They just come in whenever they please. My only issue is that my dog has severe anxiety (which they do know he's on medication for) and the outside family always has 5 of them at LEAST walk in which i am sure will send my dog through the roof.

What should i do/say about these issues?
