If you need accommodation in Edinburgh it is not short of hotels and places to stay. They will be busy around the 2nd August, though, so best to book well in advance.
When searching for hotels bear in mind that the wedding will be around on The Royal Mile a couple of minutes walk down from Edinburgh Castle. It's also worth considering that City-centre hotels are expensive and you may be cheaper getting something within taxi distance of the city centre.
