Too close!
Landing: 10:00
Off plane: 10:15
Ground transportation: 10:25
To your hotel: 11:00
To the parks: 11:30
Check in for tour: 11:30 to 11:45
The above is assuming no delays landing or taxing to the gate, no slowness getting off the plane, no checked baggage, no waiting for ride share, no traffic on the way to the hotel, a quick check-in at the hotel, a short walk from the hotel to the parks, a quick security line, and no slow/dwaddling people in your group...

And if you miss the start of the tour, you could be out the $85-110 you paid, depending on the mood/abilities of the CM...
