Sorry, I was referring to Godzilla Minus One and not Gojira/Godzilla (even the reworked Americanized version where they fit Raymond Burr into the plot).
Disney could run into an issue where the ride takes so long to develop and build that they will face a backlash for the time from announcement to completion. However, people will still flock to Avatar like mad and, if the ride is good, it will be highly popular with enough Lightning Lane Single purchases to repay its development a few times over.
