I had a similar experience, where we would spend at a full day every sprint planning the sprint (team of 5).

During the project, it felt like a bit of a waste. We were spending a full 10% of our time on project management. However, looking back, I see that a) it seems to match up with other's experience, and b) it's pretty much the same amount of overhead for project management that the project would have had using any methodology.

At least with the 1-2 days every 2 weeks everyone sees it and it's something you can get better at. I'll take that over magical GANTT charts any day.
