I agree that there's no such thing as bad publicity (to an extent) but it's not like Disney is hurting and they needed it and it's definitely not why they made the decision to overlay the tower. But your right, I'll be there to ride it and Im pretty sure I'll enjoy it even if just for the thrill factor. However, I don't think I'll enjoy the overall experience of GOTG more than TOT and it's hard for me to believe it will complement its surroundings and the rest of the park better than than the Hollywood Tower. Hotel.
A part of me wishes they made up some lame back story of the Guardians crash landing earth and ending up in the tower. That would of allowed the facade to stick around as well as the distorted jazz in the queue and most importantly, the huge tower would still fit in its surroundings.
I still can't figure out why this couldn't have been a temporary overlay. They could still get all the same buzz and synergy with the sequel but keep a beloved and classic attraction. Just look at how popular Haunted Mansion Holiday is every year. In fact, I think doing something similar with Tower every year would keep the interest peaking throughout the year. Eventually the buzz for GOTG will die down and lines will be similar to what they are now. But if they split GOTG and TOT every year. 6 months each or even 8 and 4, that would be a no lose situation. Oh well.
The only way a temporary overlay doesn't make sense is if the plan is to completely get rid of Hollywoodland.
