For us, without a doubt, its Wilderness Lodge. We've stayed at all 3 one time or another and here's our take: AKL, least of our liking, to far from the glitz and glitter of WDW, AK closes at 5 pm then its back to the resort for nothing to do, then its bus everywhere to find something to do. Long walks through the halls if you rooms at the end of an arm to the food court or lobby and as for Savannah Rooms, we had one, free up grade, and saw a few animals only at feeding time, not worth paying for and when they are not there its just a mauled over woods, not a pleasant view for sitting on the balcony.
Polynesian Resort: This is a very fine resort, we like it alot, windy walking trails around the resort, you can walk to the GF and snoop around, Kona Cafe has great meals and the pool is small but fun. Transportation is great, big ferry, small boat, bus or monorail to where you're going and great views across the lake of the MK. Recently we just couldn't justify the high price, I mean high price. When we can snag the 40% AP discount is was okay but now for our money to stay in the MK area longer, we like the WL.
WL, great themeing, great pool, on the lakes so transpo to FW, again great dining there, CR boat ride to gain acess to monorail for shoppimg or EPCOT and buses that haven't been a problem is 10 stays. Being around the 2 lakes seems more exciting, easier methods and picks in travel in the evenings when the parks are closed. Dining is good but you're in touch with 4 other resort areas and again its the location. We like the MK, stays open usually the most and latest and its only 15 minutes away. that all said, and either using a
AAA or AP discount, we can easily take the savings from the Poly and spend 10-12 nights at the Lodge, Wilderness, and relax and see everything at a leisurely pace.
Thats our take of the 3, others have their views but we rather spend more time on property and enjoy the surrounding since we've spent a considerable sum on travel to get there, and a 4 or 5 night stay isn't worth it with all there is to see and do. And let me tell you, staying at the WL for 2 weeks is sheer heaven, days to enjoy the resort and pool, a day for DTD and resort shopping with a park schedule looming overhead and just being on a Disney vacation without a daily plan is a whole different ballgame. We buy AP's and its nothing to take the boat to the MK, and just grab some hot dogs from Casey's and a funnel cake and return to the resort, or go to the CR and monorail to the lounges in the loop ,and a special for us is boat to FW, catch the EWP at night and pop into Crocketts Tavern for pizza and beer and see the horse barn.
