Took me less than an hour to see Bordlerless and again less than an hour to see Planets. Both located fairly close to one another and both were still open as of 6 weeks ago. I believe one may be closing or has recently closed.
By far the best art experiences of my life. But I like sound and lights, and all that is ultra modern, so it suits me.
Planets used to sell VIP tickets where you could skip the line but going to Borderless on a weekday yielded a very short wait as well. Suspect those of you experiencing long lines and crowded interiors are just going during peak times. Highly not recommended to do but the exhibits themselves are highly recommended by this Japanophile.
