Hi ledkr,
We have been going to DLP regularly for 19 years, both flying and by Eurostar. Both have benefits for us, living within a 2 hr train journey to London, and about 30 mins from Southampton airport. The best option can depend on where you live. Eurostar can be more expensive for us as we have to buy train tickets from Bournemouth to St P. Sometimes we travel to London the day before, and stay in a Travelodge near St P to save getting up so early.
We get there more quickly by air, as we can arrive in CDG airport at 09.30, and with a private transfer booked, arrive at our Disney resort hotel by 10.30am.
The direct Disney train from St Pancras/ Ashford/ Ebbsfleet leaves St P at arouind 10am arriving in Disneyland MLV Chessy station at 1.30pm. Using the Disney Express Service you can hand in your luggage at the DES desk in the station, and go straight into the parks. They take your luggage to your hotel to collect later when you collect your room key. It does not matter how late you get back as reception is 24hr ( we have collected ours at 1am in summer ).
When flying home, you must allow 3 hrs from leaving resort to your departure flight time, whether you are using the VEA bus, private transfer or fast TGV train, as there can be long queues at CDG for security checks and passport control, then a LONG walk to your departure gate. Not worth cutting it too fine and missing your plane. We leave resort at 6pm for a 9pm flight, and are home by 10pm, so not too late.
The return direct Eurostar leaves Disney around 7.50pm arriving at St P at 9.20pm. If using the DES service, you hand your luggage in at your hotel luggage desk, ( before 10am ) and they take it to the railway station for you. You need to collect it about 45 mins before your train time, before going through passport control and security, and boarding the train. By the time we have caught 2 underground trains to Waterloo, then caught a train to Bournemouth, then driven home, we don't get home until around 00.30 or 01.00 so much later than flying.
To get the most from your trip, advance planning is essential. Most bad reviews that I read are because people knew nothing before they went, and had no idea of what to expect, and seem to have missed a lot, or they went at a very busy holiday time but did not expect long queues for rides.
There is a forum especially for Disneyland Paris on Trip Advisor. I and other posters who know DLP very well can help with anything you need to know.

You need to compare prices, and try to book when a good offer is on. Disney have just released a 25% off offer, as well as free nights and 30% off weekends at Davy Crockett Ranch ( offsite, need a car ). Kids 7 and under stay and play free. Sometimes they have kids 12 and under stay and play free. Earlier they had a 40% off hotel, tickets and transport offer with kids under 12 S&P free which was good. Sometimes they offer free dining. You can't tell in advance what they are going to offer, you just have to check the Disney website, look out for adverts on TV etc, and try different dates and hotels for the best price.
Staying in a Disney owned hotel or Hotel Elysee in Val D'Europe gives you extra benefits like Extra Magic Hours in the DL Park in the morning from 8am.
Sometimes I book directly with Disney over the phone, sometimes through my local Travel Agent, ( who gives me another 5% off ), sometimes with a preferred Disney agent, ( like Thomas Cook ) and last January I booked a train/ tickets/ hotel package with Eurostar ( Expedia ) as Disney had no availability when I phoned 4 days before for a spur of the moment 3 nt / 4 day trip. I got the hotel I wanted ( Cheyenne ) as well as the direct train.
Be aware that Spanish schools break up for summer from 22nd June, so the parks will be busier from then, and more busy when the French break up on 2nd July. Try to avoid Public Holidays, and weekends, as parks are more crowded. ( 2nd, 12th, 13th, French. 9th, 13th, 23/ 24th Spanish ).
Fantillusion electrical parade and Fireworks do not start until Summer Time 9th July so don't expect to see those in June.
