We just did our first DLP trip, so I will answer a few of the ones I can.
We flew in from Berlin (visiting our DD who was studying abroad there this fall) on an early flight, took a private car service straight to the Marvel hotel. One of our two rooms was ready at 11am, so we dropped all luggage there and went to the parks. We purchased ride access ride by ride that day.
We planned to do Ultimate Access the next day (our only full park day), but then it was very cold (40) and drizzly that day, and we did EE so got several rides in that way. We didn’t want to spend the entire day in the park (as we would have if the weather had been better), so we added up the price of the rides we wanted, and buying them one by one was cheaper than Ultimate. One by one is almost always instant return time, so the Ultimate doesn’t save a lot of walking because you just walk up, by the individual LL and ride when buying one ride at a time. Also, I can’t ride all of the E ticket rides due to motion sickness, so it was definitely cheaper for me to buy ride by ride. You can buy Ultimate on the day of; I am not sure if it runs out?
On check out day, we had a 6pm flight to London, so we did EE, came back around 11:30a and packed up, asked for and received noon check out (one hour later than normal check out), and then left our bags in the rooms. Then you can call Bell Services, and they will come get your bags and store them until you are ready to leave the hotel (we didn’t have to be present in the room to have the bags picked up). We told them when our car service would arrive to take us to the airport, and Bell services had our bags pulled and out in front of the hotel at that time, when we returned from our morning in the parks! I wish the DLR hotels had this service!!
We considered the train, but it was more expensive for the 4 of us than the private car service. And the train only came every 90 minutes, so if it was late or we missed it, we would have to call an Uber. Also, with the 10 minute walk to the station with our luggage (in the cold and rain, getting us and our luggage wet) and waiting for the train and then walking through CDG, the transit time was about the same as the car. The car service was prompt and smooth. He even dropped us off at one terminal and one of our DDs at another (you have to drive between terminals) since she was going to Madrid and we were going to London.
As a DLR person, you may be really disappointed in the food and beverage offerings. We were sad to see very few holiday or seasonal offerings or even just interesting offerings. And some of the places we wanted to get snacks etc had very limited hours, closed hours before the park closed or never opened at all. Just know that going in, and you won’t be surprised. And the quality of the food (to us) was significantly below DLR (ie even things like Nutella Waffles which seem like they would be great in France, seemed like frozen waffles etc).
EE and staying onsite were well worth it for us. Not nearly the crowds that we see at DLR EE, by a long shot. And onsite let us come back for a break and get out of the cold/wet for a little bit. Not sure of the weather in February, but it might be similar to early December, when we just went.
Have fun!!!!
