Hi! I will be going to HK in march for 4 days.

Is it advisable to get the MTR tourist day pass to avail of the 1 day unlimited pass and enjoy the included offers? like $30 off in disneyland admission and 10% off ocean park pass?

Also, If ever i bought the MTR tourist day pass and used it let say on the 1st day, can i still avail of the 10% ocean park discount on the 2nd day?

Thanks!
