I have never really been to WDW in march, but I say go for it, camping really is a state of mind, if you are prepared, and the kids are ready to help set up, go for it have fun. Then post your trip report, I never see anyone post a trip report from FTW , I don't know if people think , we have all been there and done that or maybe I'm not looking for them in the right places, but I would sure love to read someones trip report about campground, setup, transportation, tips...etc...go for it, and then maybe others will read your report and say wow, not to bad, I'll try that. We "camp" in our travel trailer and I have learned alot from reading how other people did things. We use to have a pop-up when our kids were small and when we first started taking it out and setting up it would always end up in a fight, heat, set-up, confusion, we were such a sight, one time even had neighbors bring chairs around like we were the afternoon show , lol. After that we got our " quite" plan together, and now only use" strong" hand signals.
