I think it depends on the expectations and the length and time of stay.
I've commented elsewhere about being an OCD planner, but on our first trip with kids in 2009 we decided to go three weeks in advance -- backstory there, not interesting -- and did no planning other than where to stay (off-site), how to get there (drove from MA), how long to go for (two weeks) and what tickets to buy (10-day hopper w/ water parks). That was it. DH and I had been before a couple of times in the foggy distant past, so far as to be the pre-FP, pre-
DDP era, so I think it's fair to say that we were functionally first-timers or close to it.
We expected to wait in some lines, and we did, but if we felt like they were too long, we just skipped the attraction. We expected to not see absolutely every last thing, so we didn't mind when we skipped some things because of long lines -- we would either get them on a later day since we were there such a long time, or not and that was fine with us. We expected to not spend all day in the park, because we went in August and our youngest was 1 1/2 and still needed to nap. We didn't actually expect that we would rarely come back after naptime, but that was how it turned out - if we had been there for only a week we probably would have made more of an effort to come back in evenings. We didn't expect to eat in TS -- we did try to walk up once at Coral Reef because DH really wanted to, but when they didn't have space we shrugged and moved on. We didn't expect it to be fast to get food at CS right at lunchtime -- so we used the same strategies we use with museums, other parks, or any other place that experiences crowds around popular eating times, and they worked great. We did figure out FP- on our first day, but due to our touring schedule (arrive at RD, leave by 12:30-1), we didn't really use more than 1 or 2 at most per day and weren't reliant on them.
We had the most amazing time. It was so good that I was afraid to go back in 2011, because I was worried that it wouldn't be as awesome and would tarnish the memory of that first time.
Do I think that same experience is possible today? Yes, yes I do. I think the three important factors that helped us to have such a great time were exactly as I stated in the beginning:
- Length of stay -- we had a long time there, but could easily have had a great experience in a shorter time given that we measured our experience by what we did do, and not by what we didn't do.
- Time of stay -- we didn't go at 9/10 crowd level, we had 5-8 our whole trip.
- We had reasonable expectations, based on relatively common knowledge of people logistics at any kind of amusement park or tourist attraction, and because we weren't aiming for an unattainable standard, our expectations were more than exceeded.
