Disneyland California. It has 2 parks right by each other and 6 onsite hotels. The hotel packages include hotel, breakfast and park tickets. The park tickets are valid on your arrival day and on your departure day.
Different country websites have different deals and offers. You can book any deal currently on offer on an official Disneyland Paris website, you dont just have to book the deal from your home country website. It is advisable to avoid the USA Disneyland Paris website as it is notoriously more expensive and instead check out the deals on
