Hi,
I take the shampoo/conditioner home with me.
I occasionaly take the laundry bags to put my wet/damp swimming trunks in before putting them in the suitcase for the flight home ( i like having a lst dip in the pool before heading to the airport for a long haul flight).
I sometimes take the postcards from the stationary folder.
I have seen a note on the bathrobes ( please phone housekeeping and a new robe will be sent up for you to take away)
I draw the line at hangers/pillows/towels/toilet seats etc
Regards
TBS
