Planning to spend 4 nights at Phuket/Phi Phi island. My itinerary is as follows:

Day 1 & 2: Holiday Inn Patong

Day 3: Catch the 8:30 ferry to Holiday Inn Phi Phi island. Arriving around 11:30, check-in then hiring a long-tail boat for 4-6 hours excursion.

Day 4: Relaxing at HI PP in the morning, then the 13:30 ferry back to Phuket, spend the night at HI Patong.

Day 5: Catch the afternoon flight to HKG.

Please let me know if there are any flaws in my plan. TIA.
