Waldorf Park City (UT)
(just before Covid)
$30 credit for breakfast at their sit-down restaurant (order off menu), but you have the option to choose their Honors continental breakfast set (yogurt, fruits mostly melon, muffin, pastry, coffee/tea) which is $15+tax but you don't get charged for anything if you+1 order Honors breakfast set x2. Kids technically not free, but our server did not charge for kids.
