I'm using Kid's Nite Out.
www.kidsniteout.com
This is our first time leaving the kids, but I've heard so many good things, I'm actually excited for them and for my romantic dinner with DH! The sitter comes with a bag full of arts and crafts, toys, etc... They really make the child feel like it's a special play date.
I've heard from parents who have hired them during the day and they will take the kids to the playground, walk around the resort then out for dinner - if you wish. We'll be gone from 7pm to 11pm (4 hours minimum for the service). We're having dinner at the resort then we're going to play it by ear. If they boys are having a great time and we feel comfortable, then we're going to head to MK otherwise, we're going to stay at the resort have a cocktail and watch the fireworks from the beach.
I couldn't use the kids club since my little one is too young.
