When we stayed at the Polynesian in '03, I really wanted to stay in Tahiti. But, it was being used for concierge since Hawaii was being rehabbed. It's a terrific spot. We did end up in Tokelau which was nice also, just not as nice as Tahiti. We did watch the EWP and the fireworks from the beach area, right outside Tahiti. It was so romantic and nice.
The only time I minded the walk was if it was a downpour. To me, that is the only downside to staying at the Polynesian. Depending on where your room is at other deluxes, you could have a huge hike to the transportation area. I really didn't think the walk was all that long at the Polynesian. Try staying at Boardwalk Villas...now those rooms can be a hike!!!
We don't use the hot tubs so that's a non-issue for us. I hate being in them with people I don't know. And there is always someone in them at night.
