What I can do in this regard?

I am having a desire to go for taking the tour of Jamaica in the coming up days but on the same dates, my sister is insisting me to be with her on the niagara falls tour from new york city. I really like Niagara Falls but this time, I wanna see a new place Jamaica but she is not agreed to listen to me. Now, tell me what I can do in this regard?

Jamaica looks fun, I simply really likes to try all of these sort of the places as these and get to experience any of the mind blowing of the things as these is gonna be very much great where i surely will be learning like many of the things.
