Another vote for AFVC! In my siggy you'll see we stayed at Summer Bay Resort. BEAUTIFUL PLACE. Great pool & stuff for kids to do, but about 7 miles west on Rt 192 from WDW Main entrance. Traffic wasn't bad, but a bit of a pain if you wanted to run out to get take out since we weren't really near anything. There is a grocery store & a Denny's right next door, but that's it. FAR from anything in Orlando.
I would definetly stay there again, but just wanted to warn you in case you planned on going back to the room mid-day with the kids.
The next year, we stayed at Cypress Point Grande Villas thru skyauction.com. They are located about 1 mile from the Downtown Disney entrance. Tons of restaurants & services in the area. Our condo was even nicer than Summer Bay (hard to believe anything could have been nicer), but the resort itself didn't have the appeal to us that Summer Bay had in terms of activities & the grounds. Still very nice....and can't beat the auction price I won it at. GREAT LOCATION!! Very close to Orlando's attractions with a shortcut road we found on a map instead of I-4.
ETA: Just this week I received a postcard with a promo code for AFVC. It says: Call 1-800-724-9988 & provide your email address to get $35 off when you call to book your next Space-A or High-Demand vacation. Mention promo code 860059 when calling. Offer expires 9/30/06.
The only other "catch" I see is it says near the top "You're already a member. Now make it count. Book today by calling 1-800-724-9988 or visit afvclub.com". SO, I DON'T KNOW IF NEW PEOPLE CAN GET THIS. BUT DOESN'T HURT TO TRY.
