I've been in June, early June, midweek. I think possibly Michael is comparing the park hours/show schedules etc/lack of fireworks with the American parks?
In June there is no fireworks at DLP, ever. You only get those for around 6 weeks in high summer season, on New Years Eve, 3 bonfire nights in early November, and St Patricks Day in March.
There is no evening parade outside of high summer season and Christmas season. Park closing time outside of weekends and high summer season are rarely later than 7pm or 8pm for the main park, possibly an hour or so earlier for the Studios.
I am usually at DLP in low season, midweek. On some days in low season some restaurants are closed, and yes, when the parks close at 7pm you can't eat dinner in any of the park restaurants after about 5pm.
I don't remember missing out on any rides on our June trip - but its possible there were some closures. I do remember that the Storyboat ride and Casey Jnr were open and I think June was the first trip where we managed to ride them

.
If you plan your days knowing in advance that there are no fireworks, parks close early evening, and keep an eye on the refurb list which is published every so often on the official site and on DLRP Magic, you can still have a great stay at DLP (in my opinion). There are plenty of Village and resort hotel restaurants you can eat at after the parks close, and you don't have to be a guest to enjoy any of the public restaurant/bar facilities any of the hotels offer.
ETA - there are a few June trip reports from 2010 here, might be useful if you're thinking of going then? -
