all these buildings should be combined into a single structure not individual buildings, suggest removing the building tags from the pois and adding a new building area for the entire structure.

river should be extended

looks like there are two areas here for the same feature name: way/33261094 and way/44018930 suggest looking at these to reconcile them... maybe merging the smaller one into the larger one if they are the same but overlapping areas otherwise maybe updating the smaller area to better represent what it is to make it distinct from the larger area...

the duplicate fitness center tags on each of the 4 buildings here could probably be consolidated into a single relation if all 4 of the structures house a single fitness center complex, otherwise perhaps add more detail as to what fitness center is inside each structure if they are not all the same.

I doubt that this small building holds a motel 8: way/364846549 is it instead part of the Nirvana Hotel and the tags here can be removed?

looks like some of these restaurants are merged on to the building part areas here but they should probably be separated into their own areas if representing an indoor space as the current room tag suggests. The restaurant does not occupy the entire building part and it wouldnt make sense that the restaurant has 40 levels. I suggest disentangling the pois that are rooms from the building parts and making each have their own distinct areas: one for the building part and levels and one for the restaurant. Example of one that could be updated but there are others: way/115661799

is this raceway name known? if so it would be useful to add it or a area for the venue

looks like casino/hotel here has interior rooms mapped as walls, they should use the indoor mapping schema not the barrier=wall schema... example of one wall: way/180748305

poi for park node/5564900222#map=19/43.07230/-79.07807 is currently tagged as an attraction and seems to be further south than where its actually located, suggest updating the location of the poi or merging it with an actual park area or something to better represent this

two airport pois are here but probably only one is, suggest checking which one is still here and removing the other to get rid of duplicates...
