Stayed at the beginning of August 2016 for 5 nights, I booked two rooms and both received the Executive Lounge access and free premium wifi without asking. I also received a 4pm late checkout by calling the front desk.
The Junior Suite is probably the best in the hotel because its so open/big, also the executive room was much bigger than I expected. The breakfast in the executive lounge never had more than a few people eating which was peaceful.
The guy at the front desk let me see the Executive/Master Suite rooms and while they are nice, they probably aren't worth the upgrade because it feels a little cramped with two smaller areas but for families with smaller children I think it would be nice. I should note the online checkin let me select the Executive Suite as a free upgrade.
