we going on the same dates and I am prepared for it to be busy as the french schools break up for summer that week, hopefully it won't be to bad as the summer season would not have started yet.
Hi the best piece of advice I can give is to not expect it to be exactly the same as WDW. Disneyland Park is very beautiful, especially the Castle and it has all the magic of Disney with an European flavour!
We have stayed at the Explorers twice and have found it very clean and comfortable both times. The breakfast is fine but we don't bother to eat there in the evening, I prefer to eat either in the parks or in Disney Village. In case you haven't noticed, there is a Useful Info Thread at the top of the page here, and this site here is excellent for helping you decide where you would like to eat. If you click on the name of a restaurant, then on "menu", it will show you the menus and prices.
Hope you have a wonderful time! We're off to Disneyland at the end of July and it's usually gorgeous weather and quite busy -- like you would if you were going to WDW, it's always a good idea to have a general plan and have a great time!
As for the Explorers, it's a nice clean hotel with a great pizza place (you can takt the pizza to your room too) and a lovely pool.
