Just completed a one night stay using Cash and Points plus DSU. Was upgraded to a newly renovated Grand Executive Suite (XX25 series room) with great views.
Did not hear any construction work within the hotel but did smell paint/varnish in our corridor.
Grand Club Lounge is great with top notch service -- they catered to my pork allergy and gluten free preference perfectly.
Great hotel and can't wait to return once the Grand Club lounge reno's are complete.
