Looking to take a week odd work soon, putting aside issues like cost of the hotel etc, are there any decent coasters there, or is it all more of an exercise in Disney branding than anything else?
There are a few coasters at Disney which are worth doing if you haven't experienced them before. In the Disneyland Park you have Big Thunder Mountain, Indiana Jones and the Temple of Peril, and HyperSpace Mountain. Over in Disney Studios you have Rock 'n' Rollercoaster, and Crush's Coaster.
There are also a number of other rides which are definitely worth doing - Tower of Terror and Ratatouille in Studios, and Phantom Manor in the main park. You also have Pirates of the Caribbean re-opening on 24th July.
I would strongly recommend checking on the DLP website if there are going to be any rides closed on the dates you are looking at. The Resort are operating a rolling refurbishment programme which means certain rides are being closed for a few months at a time.
If you do stay in the area and want to experience a few more coasters then definitely look at popping to Parc Asterix which has the awesome Oziris and is only 30-40 mins drive.
