Look up Lees Ferry Anglers on the web and give them a call. They are a great resource for river fly fishing info. They have lodging, great food, an awesome fly shop, rental boats and some of the best guides on the river.
Dave Foster at Marble Canyon Lodge is also a top notch river guide.
Check the flows, because they flucuate them a lot on the weekdays. It fishes well during the rise, but you have to really watch what is going on or you will miss it. Sunday is an excellent day and that walk in area mentioned above can be a blast.
Make sure you know what the flows are, so you don't get yourself into any trouble when wading. They can rise extremely fast and catch you off guard if you're not ready.
Take a lot of film, because it is a beautiful place to see.
