This was great fun and definitely worth doing. We actually did this and Teamlab Borderless as we saw it from the Yurikamome line as we left Odaiba. There were 2 elements of Planets which were also in Borderless and there were only 5 'rooms' in total so you might want to bear this in mind if you plan to visit both attractions.
Went with my friend, so managed to have a couple of nice photos...but most of the rooms are dark, so it's gonna take some skills. On the other hand, you can just enjoy the experience and contemplate on the feelings the artworks evoke. Only phones are allowed inside, so didn't bring my pocket wifi. The place has wifi but I had some difficulty connecting, so wasn't able to use the Teamlab app much inside.
