How do the French currently view DLP in terms of it's value for money?
I'll try to answer that one, since Bastia and I are both on DCP (french forum)
Value for money ... well, more money less value. That's what many think. Of course you will find people who will invariably get excited for everything Disney, so, well, it's hard to say.
I can't say that we have an unbiaised opinion, because we are fans and regular guests, so we're more prone to seeing the little things that make us rant

But one things is for sure, it's that we are still here. So it means we are still enthousiatic and that we get our Disney fill despite some not-so-good things.
As for the general French guest, before talking about value for money, we need to talk about marketing policy at DLRP.
The tendency is to offer deals and bargains in order to fill the parks up with guests. So people will get tickets and packages for pretty much less money.
But on the other hand, rides and attractions are aging, overall maintenance is not what it used to, and we are yet to get new rides, attractions, and shows.
So more people, but the same amount of things to do.
Now how do you measure value for money under those circumstances ?
Prices sometimes go down due to deals and flash sales, and value is on the decline (as you may note on the lows on some TRs here)
So overall the value for money is maintained, but I tend to think it is artificial and cannot last for long.
What fans truely expect is that 20th anniversary will see much improvements in almost everything at the parks. There are some skeptics who think DLP won't be able to pull it out. But many are also really confident that 20th anniversary will make things better.
There is one lingering question on the French forum Bastia and I are roaming (and many more members here actually). Basically it asks if DLRP has lost of bit of its magic ...
I can only give you my answer : yes, it is on a downslope, but is it because I'm a regular ? How would it feel it I only went once a year or even less often ?
DLRP is not as shiny as it was back in 1992, and it's certainly not as glamorous as WDW.
But still we have a better "MK" (even though ours is called
Disneyland), and one of the big differences is in distance and how big WDW really is as compared to our Paris parks.
But a visit at Disney's is always something you will enjoy if you come there with the right spirit.
French people, on a general basis, will find that DLRP is overpriced, but we still go, and in numbers.
BUT, more and more french people like me consider skipping DLRP, and using the money to book a trip to WDW. For we consider that it would be better to spend 2 weeks in Orlando every year or every 2 years than going 10 times to DLRP on the same year.
I did 25+ days (max 3 days in a row) at DLRP in 2011, I guess that's why I'd prefer some Florida sun for a change.
But once again, remember that, as a member of disney forums, I may not be representative of the general public who does a one-shot trip to DLRP
But if I were to speak my opinion on what the French general public feels, it would be like "Oh we had a great time, that was awesome, but geez that cost an arm"
