Seriously - the Star Wars Hotel already means little in terms of overall attendance gains or losses at Universal, and you know why? Because that sort of experience is great, but no family I have ever met would even consider it based on the cost and the fact that the target audiences for the parks are not, at least as of now, mainly rich people. They are targeting families, and in some areas, massively nerdy fans - who have proven willing to spend in the past but with IPs which until that point, were untapped for extensive merch.
Any way you look at it, niche experiences like the Star Wars hotel will not make Universal regret making new and larger investments in the park because they will still get a large ROI.
