I had PF for 2 years (did 2 WDW trips with it), but it's been gone for about 1 1/2 years now.
Here's what helped me...
1) Always wear shoes
2) I used "heal that pain" inserts from the internet, offered some relief

3) stretch before getting out of bed
4) stretch before and after walking
5) roll arch and heal on frozen bottle of water (every night or even 2 per day if you can)
6) take over the counter anti-inflammitories (advil)
7) most importantly - strengthen those leg muscles!!!!!!!
From what I understand from my doctors, PF is caused by the calf muscle and muscle that runs the bottom of the foot both being "shortened" from lack of stretching. When they are then stretched (by walking) they cause pockets of irritation where the tendons attach to the bones. These pockets cause the pain. The ice and meds ease the inflammation, but stretching and strengthening the muscles is what will heal the PF.
We bought a "gazelle" excersize machine and that's what healed mine. It's gentle, repeatative stretching and strengthing the muscles healed mine within a few weeks. This same machine worked for my mom's too. HOWEVER, my understanding is that you can get the same results (healing) by doing toe raises off of a step. I just wasn't dedicated enough to do them often enough and enough of them.
I don't know about your's but mine was "ok" WHILE I kept walking, it was when we'd stop to eat or take a break that getting going was PAINFUL. While at WDW, I HAD to make sure to stretch often, take advil, and do the ice at night and morning, NO MATTER WHAT.
Pixie dust to everyone suffering with PF
