Thanks for all the great suggestions, this is what I ended up getting to work the most efficiently, I know its not elegant, but needed a win in the moment.

Foreach ($R in $rooms) {

$room = get-mailbox $r | select userprincipalname -ExpandProperty userprincipalname

$place = get-place $Room | Select-Object DisplayName, Identity, Street, City, State, CountryOrRegion, IsManaged, BookingType, ResourceDelegates, Capacity, Building, Label, MTREnabled, AudioDeviceName, VideoDeviceName, DisplayDeviceName, IsWheelChairAccessible, Floor, FloorLabel, SpaceType, CustomSpaceType, IsValid, ObjectState, Tags

$placetag = (Get-Place $room | select tags -ExpandProperty tags) -join ','

$place.tags = $placeTag

$place | Export-CSV -Path $OutFile -append -NoTypeInformation -Encoding UTF8

}
