DENVER (AP) _ The visit of Prince Philip, Duke of Edinburgh, won't be stuffy, although protocol will be a concern, organizers say.

''The types of arrangements you would have thought you needed - opulent place settings and red carpets - are not needed,'' said Judy Arbarbanel, director of marketing for Colorado Outward Bound School.

The school will present the school's Kurt Hahn Award to the prince on Saturday following his arrival in Denver.

''He does not like large crowds of people at the airport,'' she said. ''He likes informal situations.''

But the desire for simplicity did not eliminate the need for detailed preparations to make sure the event goes smoothly.

''We had a very short time to prepare for this sort of dignitary,'' Arbarbanel said. ''Usually you would have a year to prepare for this sort of visit. We had four months. ... We feel we have everything under control, but we still are looking over our shoulder.

''Our image is very laid-back, and what we're doing here is very formal,'' she said. ''We learned some very interesting things.''

Protocol has been a concern, she said.

Royalty usually initiates the conversation, one is not supposed to ask them questions or touch them, and a bow or curtsy - while not required - would be a nice gesture, she said.
