This tunnel set is nice because it allows for tea parties and hanging out in the center section (plus Mom can check on what is going on through the upper viewing window). The whole set packs away flat in its carry bag for storage under a bed, or in a closet.
The minus is that it can be a bit of a pain folding and securing the three, extremely short ties on each tunnel in order to pack it away. Tying without making knots is a problem. I bought some double-sided velcro straps which I use instead and I can now quickly pack it all away without frustration.
Of course, a couple of cardboard boxes and a table covered with a blanket can be just as fun too, not to mention cheaper…but boxes don’t store as nicely!
