I went to Peleliu in 1988, so my info is rather dated.
It was a cheap flight out of Manila. And I only found out after I got there that this particular island had been the scene of the fiercest fighting in the Pacific campaign during WW2. As I was strolling along a beach, there, leaning up against a tree was an unexploded mortar round.
When the islanders returned after the fighting, they were horrified to find the landscape completely changed and body parts everywhere. The US troops drove the Japanese back into underground caves (which they had probably burrowed out), and they would not surrender, so they sealed the entrances with explosives.
But don't let that put you off
. It had a very relaxed ambiance, as you would expect from an island so far out in the Pacific.
Almost all vegetables were shipped in as the locals are not big on farming like South Pacific islanders. So as you'd expect, things were quite expensive !
And it was then still a US protectorate, using US dollars as currency. So I'd utilize Google a fair bit for current info, if I was you.
