Feb. 23, 2011 -- Party-loving Prince Harry is planning his brother's farewell homage to the single life, but some things are off limits for Prince William's bachelor party, ABC News' royal contributor said.
"[Prince Harry] made a secret plan with the guys that run one of the best water-sports companies, and they're going to be out with speed boats, wake boards, water skiing; spend the whole day basically on the English Channel having fun," Duncan Larcombe said.
Drinking is prohibited on the water, but part of the intent of a bachelor party is to get liquored up. So a private pub crawl is being planned for the end of the day on the last weekend before the April 29 weekend.
"They've put a lot of thought into choosing the right place for the stag and one of the concerns that they had is being too public, so what Harry's hatched is the plan to speedboat at the end of the day ... go up the river to a couple of little pubs that are only accessible by boat or on foot," Larcombe said.
To set a tone of discretion, they have decided not to go to South Africa, but instead stay in the United Kingdom.
"One of the other plans they looked into was to rent or stay in a French ski chalet in the French Alps," Larcombe said. "I think William's made it quite clear that while Harry's doing the plans in secret and it's all a surprise for William, he has set ground rules: not too lavish, nothing that's going to get him criticism at home and abroad for spending too much money when the economy is not rosy."
The guest list is 20 good friends of the future king of England.
"The people going on the stag weekend are absolutely the inner circle, William's closest friends, a couple of guys from military, his colleges, and guys he's known since growing up," Larcombe said.

Discretion doesn't end at the honeymoon: William and Kate Middleton are looking for a private place to spend their honeymoon as well.
"I've been told that wherever William goes [on his honeymoon], his plan is to go somewhere where the local laws in that country make it illegal to take pictures and publish those pictures without the permission of the people involved," Larcombe said.
"That will allow Will and Kate total privacy when they go away."
