I am looking for a solid, good quality insect hotel. I've read that these hotels are a bit of a fad and people sell not so great insect hotels. Does anyone have a recommendation?

Well I'll be...never heard of that before. Here in Florida they have no problem making anything and everything a hotel for their needs, even my house.
I'm sure you could find that on Amazon.

I was speaking to my dear husband just today because he wants to get one to keep the carpenter bees away from our shed.
I said I didn't think they would work because the bees like picking their own place and digging their own hole

I'm not a big fan of them. They're often built poorly and look like they just threw in whatever was around rather than think about their potential for use and adding capacity that way. So, I make my own and typically don't mix the various types together.

Pick up a bunch of sticks of different sizes, cut them to size, bundle them together with steel wire and put said bundle in a secluded spot in the garden. A couple piece of rotting wood will also work wonders.

Insects don't like these "hotels". Here are a couple of gigantic ones I've seen in France:





They must have cost the department a fortune and there wasn't a single bug around them. Talk about tax money at work.
