i was thinking about this myself,i dont think you will be in for any problems.theres no doubt that they will be aware of any problems that could arise and will have prepared for it long in advance. As has previously been mention,where the park is situated is also a positive thing as,due to the nature of the riots,they are mainly based in poor areas where unemployment is high.
A curfew has also now been imposed,and although this has been ignored by a minority,this has had a positive effect on the number of people rioting.
I think it will actually be a positive thing for anyone going to DLP from the UK or other foreign countries. I know the riots are an unfortunate thing,but the majority of people who go to DLP are from France,and these riots and the reaction of french government and police are going to have a large effect on consumer confidence,and a big effect on the number of french people going to DLP.Not to mention people from other countries who cancel their holidays due to concern for their safety.This means the parks are going to be quieter.And,with the parks being quieter,it should make the whole experience much better for you and your family,nobody likes to queue after all!
The reality of the situation is that this is a very safe time to go. Much like public reaction after the September 11th terrorist attacks,millions of people refused to fly in the following weeks due to concern over their safety,but the safest time to fly was September 12th.The security all over the country after the attacks was so intense to prevent anymore attacks.Its the same sort of thing in France,there will be a huge increase in security and the number of police patrols because of the recent rioting,which will make it a very safe time to be in DLP.It,should,make DLP and the area around it a very tranquil place to be in.
One thing i would worry about is the curfew imposed on everybody in France,and whether this will effect you.I dont know if it will still be in place when you are there,or whether it concerns you as a tourist,but it might be a good idea to find out if you need to be back at your hotel by a certain time.
Hope that is a help to you.
