I was taught two things when building a miniature version with the kid in a forest education center:

- after drilling holes, make sure to smooth the edges; insect wings could get stuck or damaged on unnaturally rough edges that the wood drilling bits leave. - best to place the insect hotel with the openings facing west

This also depends on the local climate and wind direction. Here it is recommended that the holes face south. That helps against rain which is commonly coming from west as this is the prevailing wind direction here.

Apparently it is also recommended that the holes be of different sizes, rather than uniform.
