You need a whole day here just to see everything as they have massive wait lines. To get into the floating cloud was 70 minutes and they would not let you sit down whilst waiting in line resulting in very sore swollen legs and aching back, the wait wasn't worth it, you lie down on a net, watch a two minute video projected into the ceiling with music. Disappointing so skip this one. The rest were all good but still more lines.
Very interesting place and ever changing. Multiple floors with different activities and things to see. Not all of it is suitable for everyone as some floors have variable lighting, floors, and activities (like climbing) but there is something for everyone at all ages and just sitting in one place will still give you quite a bit of variety. Some of the exhibits are interactive though and each room is a little different so it's well worth wandering about. One thing to note about this tour in particular is that the driver literally just drives you there. The voucher to access the museum is sent via email and a link. Also worth wandering around the area (Odaiba) as there are several other things nearby worth seeing as well as restaurants and a ton of shopping (Venus Fort and DiverCity).
