We were going to attend so booked 2 hotel rooms here
http://www.marriott.com/hotels/trave...riott-marquis/
But we have so much things on right now that the three people attending are now required in the office. Rooms are from April 10-13 and are $115 per night.
1 x King Bed room
1 x 2 Double Bed room
Its within 3 blocks of the convention center of where Ad-tech is I believe. Worst case scenario we'll just let them run.
Get in touch if you could use 1 or both of these rooms.
