Apart from the roads within the Peter Island Resort there are no roads on Peter Island. Contact Prospect Reef Resort , Tortola, about possible ferry schedules to the island.
Phi Phi have the most beautiful shade of water around and the surroundings are just stunning - but underneath there's a lot of trash. Locals don't care about collecting rubbish and saving the environment too much unfortunately. There are many local restaurants and places to visit which is nice.
Phi Phi are considered to be somehow luxurious. There are expensive hotels and restaurants but you can find these places reasonably priced as well. The islands are beautiful, many places to see, loads of beaches and many many tourists.
