One of the best things about our brief stay and visit at Uni....was that it was what WDW used to be. Dining didn't need 6-month reservations, the overall vibe was just more relaxed....for us, from everything like checking into the hotel (no long lines.....just strolling up to the desk), to heading down to the nice restaurant in the hotel to be seated right away for a great meal, to wandering the parks easily and (with the early entry and Express Pass dealio) enjoying a wide variety of attractions with little waits.
And WDW used to be that way. I can recall on a trip maybe 14 years ago (?....our first stay at AKL). Our waiter at BOMA asked us if we had ever tried O'hana, and mentioned that if we had not, we needed to on that trip.
We were able to, without any troubles, stop in for dinner there one evening based on his suggestion. None of our dining plans were made before a particular day....we'd decide that morning where we were headed, and made dining plans at the concierge desk (if we felt like it) for that evening, based on where we planned on being.
WDW has lost so very much of that impulsive feel.....planning and reserving dining, planning and reserving attractions, carrying around the smartphone to constantly be abreast of all those reservations.
That's not a vacation.....that's everyday life with some rides thrown in, and perhaps netter scenery than a cubicle.
I go places to get away from that level of regimentation when I can.
