The UK tends to do the best out of the
Free Dining Offer. For the past fews years, Free Dining is available for stays at any stage, bar a few weeks over Easter and December. This year is following the same trend - Free Dining is valid for stays 5 nights or more from Jan 1- Mar 30 and Apr 17 - Nov 30 2017. I don't think I've ever seen anywhere else have as generous an offer.
It's also worth noting that UK Travel Agencies are also reporting the the QS and Regular Plans are going to see the addition of an extra snack, whilst losing the dessert element from the Quick Serivce Meals. Up to this point the Dining Plans have been the same across the board so Im interested to see if this change will be across the board too once the 2017 Dining Plans are officially released. For my family, an extra snack as opposed to the dessert with a QS meal works a lot better! Both sites below have details on the changes
