It should be a little longer than that. The moment the engine stops there is a weightless sensation. There will be some form of movement when the capsule releases from the booster too. After that, the weightless sensation should last until the drogue chutes deploy. There will be some time used to get into and out of your seat during that weightless period but it seemed to be a lot more than 1 minute and 23 seconds.
Here is the timeline:
liftoff 0:00
MaxQ :50
MECO 2:20 weightlessness - still in seats
Sep 2:40 free to get out of seats
Apogee 4:05
Touchdown booster 7:30
Capsule drogues 8:15
Capsule landing 10:10
So I'd say you'd get about 5 minutes of good weightless playtime and a little less than 6:00 of weightlessness. It all depends on how much time they give you to get in and out of your seats. The capsule hitting the denser part of the atmosphere would generate some feeling of weight.
Overall, I'd take New Shepard over Virgin Galactic any day and I expect that the price will be less for New Shepard than VG too. If you just want the sensation of weightlessness then the Vomit Comet costs $5400 for 15 weightless hop maneuvers at 20 to 30 seconds each. So 5 minutes of overall weightless time. $156K to rent the plane for an exclusive flight. You don't get to the edge of space and you also are officially an astronaut with New Shepard since you technically went to space.
