I started posting to WordPress using the iPhone before I did it directly from my computer. I must say it isn’t as intuitive, but it is possible to stay in touch that way. Just keep things simple, and you will be fine. We’ll be anxious to see what you are seeing, so don’t be shy about trying it out. Give it a whirl before you leave home, so you can do it in a relaxed atmosphere to get the hang of it. Bon Voyage! ;->
