RockOn! Registration

Time to register for the 180th National Puzzlers' League Convention in beautiful Boulder, Colorado. Play puzzles and games from July 11-14, 2019. The festivities will be held at the Embassy Suites by Hilton Boulder, a centrally-located hotel with free breakfast and happy hour. Boulder is a big small town, nothing is more than about 15 minutes away by car. The hotel is within walking distance of many restaurants and services. Downtown Boulder’s Pearl Street Mall is only one mile away. Trailheads for great hiking, mountain biking and horseback riding abound. Warm summer days are perfect for exploring Boulder Creek via innertube, rock climbing the spectacular Flatirons that loom over the city or enjoying the arboretum on University of Colorado’s campus. Boulder is located on the foothills of the Rockies and can be wrapped into a longer trip to enjoy the mountains.

The deadline for convention rates on hotel rooms has passed.

To reserve the Embassy Suites for $229 a night, use the address https://con.puzzlers.org/rockes or call the hotel at 303.443.2600. Krewe may also register at the Hilton Garden Inn across the courtyard for $189 per night (no breakfast) using the address https://con.puzzlers.org/rockhg or call the hotel directly at 303.443.2200. Both hotels are brand new and we will be using facilities in both buildings. Book early, as this excellent rate expires on June 18th! After that date, the rate will skyrocket to normal Boulder summertime rates north of $400.

The con fee is $275 and will cover three meals (no breakfasts are provided) and the Wednesday picnic at the hotel will overlap the free happy hour from 5:30-7:30pm on July 10th. Please email if you have any questions. See you there!

The con registration deadline is June 18th
