it's good if you take both the parks so as to maximize your stay there and come back with them or else you can always take the train back if you finish early with one park ticket.Do the Disney park if you one park ticket,they will recommend that too.

11/5/22 the meet up location was at the end of the street towards the back end of the street of the Pullman Paris hotel. Location about 5 minute walk from Eiffel tower. We got our tickets before boarding the bus from the guide and took us about 45-50 min to get to Disneyland by shuttle. Park opened at 8:30am. We did the park hopper and thought that was perfect to do for an all day activity. We took our time and still managed to finish both parks by 4pm and rode a decent amount of rides. Park wasn’t that crowded for a Saturday. Been to other parks on a weekend and it’s usually terrible to get around the crowds. Got to catch 2 parades (one Halloween one). We didn’t stay until the end to catch the 9pm bus so just took the train back to the city at 5pm which took about 1 hr and was about $6 usd per person to get back. The fireworks is at 10pm if you’re willing to stay that long but jet lag got the better of us

The guide was an impressively polyglot person, mastering English, French, Spanish and Italian as well. The ride there was OK, but the bus for the return trip from the parks did not arrive punctually as agreed. This aspect and the allocation of the guests to the multiple vehicles - which was sort of chaotic - gave us the impression of disorganisation. There was no problem with the park tickets themselves. Overall recommendable if you are looking for a convenient bundle solution for getting to and from and entering Disneyland.
