Help please-I want to take my nephews 10 and 13 for their birthdays if possible, to Silverwood as heard it is a fun place. Would drive from Seattle. (not sure how far) Please recommend "closest" and nice hotel/motel to Silverwood for the least amt of driving back and forth, and what you might recommend. 2 nights, 3 days? Buy package from hotel or Silverwood? This is a birthday gift for both boys so want it to be special. Planning to go weekdays in August. Thank you for any advice possible.
