We just returned from 8 days at WL concierge and LOVED. It definately was worth the money for us. We had some special circumstances that I won't get into here, but if we had not been on concierge, I know we wouldn't have been treated like kings and queens! (circumstances had to do with ALL of us being dreadfully sick during part of our stay....I ended up in ER for 7 hours getting IV fuilds)
The breakfast is GREAT. We are not big breakfast eaters, so it was perfect. The croissants were melt-in-your-mouth delicious and HUGE> So were the muffins. DS5 has to have chocolate milk and this was brought up for us several times a day. (it's like $1.99 at roaring forks!). Other selections were bagels and cream cheese, English muffins, little boxes of cereal, hot water for oatmeal, and of course drink selections.
Middle of the day IS just snacky stuff..... gummy worms, mixed nuts, pretzels, etc. and beverages.
Dinner time was always a GREAT hearty soup, several cheeses and crackers, fresh fruits, fresh veggies and dip, delicious bread, and a hot ENTREE.... at least when we were there.....one night was roasted chicken with red peppers and penne pasta in a light red sauce, another night was beef stroganoff, etc. I can't remember all of them, but they were not appetizers.
Desserts included huge cookies, Magic Cookie Bars ($2.25 at roaring forks), warm fruit cobbler, warm apple crisp, forsted brownies to die for, little cheesecakes, several wines, Bailey's Irish Cream, Kaluha and milk, etc.
We have always found the CM's there to be fabulous and the food selections to be outstanding. We have also tried Yacht Club Concierge and were VERY disaapointed in it (this was several years ago). And Poly Concierge, which we liked very much.
WL concierge is all on the 7th floor and is accessed by sticking your room key into a slot in the elevator. This is the only way the elevator will go to the 7th floor.
For us, WL concierge is always worth it. We also had a fabulous MK view! I'd say go for it, but it's just my opinion!
