Yes, you should prepare yoru round-way air ticket and proof of enough fund for your stay in Hk well.

Philippine Citizens travelling to Hong Kong doesn't need a travel Visa provided they stay up to 30 days.

Sorry, I just made a mistake. Paul is right that filipino passport holders are exempt from visa to Hk, but only for 14 days at most. However, you are not allowed by law to take up employment (paid or unpaid), to establish or join in any business, or to enter school as a student during the visa free period. If you will stay for longer than 14 days, you will have to apply for a visa.
