Windows CAN be opened at this hotel for fresh air.

Im very glad they have an executive lounge, as this is rare for a Doubletree property, however, evening food at lounge is only a small selection, of which only 1 option is warm food.
Definitely not enough to substitute for a dinner.

Gold & Diamond members can order freshly prepared items from the a la carte menu at breakfast free of charge.
This is in addition to the full breakfast buffet which is also free for gold & diamond members.
