Just got back this week from 12 days in Kauai, first since 1986. We had a great time and used much of the advice from all of you here plus Ultimate Kauai and Underground Kauai. We were very pleased with Embassy Resort, two bdrm units were very nice, and staff at front desk, housekeeping and concierge were great. We were able to switch from nice pool garden view on 4th floor to 3rd floor ocean front on third day. Our last five days were at Sea Lodge in Princeville, a much smaller 1 bdrm unit that was small but adequate with great view of the ocean and lighthouse.
We did make it to Tidepools for my wife's b-day and to Beach House for our anniversary. Both were nice, although we couldn't get window table for dinner at Beach House, so we settled for lounge window seat, and then had dinner on patio after sun was down.
Keokis Paradise was nice for late lunch-early dinner, and also made it to Jo Jo's twice. Who would have thought ice cream with shaved ice was worth trying? Yum.
Although not big snorkelers, and fighting sore ear, we did go to Tunnels twice and it was very good. Didn't try Poipu so can't compare. Survived Inter-Island Heli tour w/o doors and it was ok. Tough to take photos that way. Princeville Hotel is very nice and we were over there for shooting sunsets a couple of times plus their hula show on Sunday night.
When I get organized, I will try to post some photos or whatever. If anyone has any questions, just ask.
