DH and I - just went on our own, without a tour guide group - I'm a planner... so I just did my thing...
I used Rick Steve's book on Paris, and a couple of other books, Triple A books and maps, did a ton of research, watched alot of You tube videos, Travel Channels, learned some basic French to get by, lots of good info on the Paris board here on the Dis...
We used the Concierge in the hotel, to help us book semi private tours, get us bus and museum passes, as well they gave us maps, made reservation for a Boat dinner Cruise, and Eifel Tower tower tour, Dinner reservations... I knew in advance what we wanted to do and see, and accomplish while in Paris. As well as solid advice on where we should and should not go... the Yellow Vest movement was happening, the trains and airlines were striking... they helped us navigate around...
The Dis'er helped me with a car service suggestion, and it worked out so beautifully...and tons of other really great tips, and trip reports...
It was nice to able to stay somewhere longer, or leave when your ready to move on without having to wait on everyone else... or just stop and have a drink in a cafe, even head back to the hotel when the jet lag hits. DH and I prefer to travel without time constraint's... Vacation time is sooo precious, and we like to streamline it into what we want, so we can make the most out of it...
By me planning, were able to have the trip we wanted... at the pace we wanted...and use that extra money for other things while we were there... like 3 days at
Disneyland Paris, Hotel and tickets and the half meal plan... Private cars... semi private tours, and lots and lots of really nice wine!
Since you are not looking till 2022, you have time to plan...
You know your family best, and you know how you like to travel, so I say go with how you like to travel, the amenities that you enjoy, looking at everything that is included really looking at what is offered, and most of all what's not included...
For instants what does breakfast consist of? is it a European breakfast or and American style breakfast. What is on the menu options for lunch.. So friends on a tour, they stopped at a cafe, and basically lunch was a half sandwich and about 6 bites of soup... they could upgrade for a whole sandwich and full bowl of soup, it was more than if they had just ordered it off the menu? ... What is allowed at dinner, open menu or set menu... this things are what you have to stop and look at... while the price might seem great... what are you really getting for that price... what are you going to have to pay extra for...
Run the numbers and re run them... you have to get a true cost analysis...
No matter how you decide to go... Happy Planning...
