Doris,
I agree...start walking now. If you have a nearby mall, you may be able to walk indoors (many malls having "walking clubs" that enable you to enter the mall before it officially opens). You'd be surprised at how far you'll really walk while at Disney.
Here are a few tips:
- Take extra socks! If your feet start sweating or get wet, you'll be happy for the dry socks, which will help minimize blisters.
- Pack a very small first aid kit... something as simple as band-aids and antibacterial ointment. While you can visit the nurse, it's usually more convenient to sit down and take care of blisters asap.
- Don't laugh...but if your legs rub, be careful of chafing!!! You may want to wear longer shorts than normal, or take some gauze pads. If you're sweating and doing a lot of walking, you could get blisters between your thighs)...now, quit laughing!! I know folks who've had this happen and apparently is quite painful (and who wants to ask the nurse to put band-aids there?).
- Make sure you carry a water bottle! The stands are great about giving you ice and you'll enjoy the lovely icy cold water (it tastes great and feels good to splash on your face)...speaking of drinking...you may want to steer clear of sodas.
- Wear a hat... just keeping a cool head (tempature-wise and otherwise

) is a big help.
- If you're staying at the Park, don't feel bad about taking a noon-day break...head to a water park, the hotel pool, or back to the room. A quick, cool shower does wonders! You'll be refreshed for round two.
- Remember that the folks who are telling you that you're gonna fail are probably just green with envy (who is going and who is staying home???).
I hope you and your family have a wonderful time!!!
