This is perfect, and my grand-babies love it!  Yes, it takes a long time to put together but we are pretty good at reading instructions so it was not a problem for us.  Took about 5 hours for 2 people.  Definitely need a helper and do not use power tools.  They give you all the tools you need.  Also since there were a LOT of pieces, it was helpful to put each "letter" in a small bowl and label it rather than trying to fish through the multiple bags.  Overall, it is great and we love it!
