Couldn't agree more with Matt (aka Schwanzee)
We usually rent a house too. But having the boat in the water and not having to f*ck around with launching is kind'a nice. Plus the London Bridge has suites that over look the docks/water. Kind'a nice to be on the water. And there's Kokomo's and the martini bar under you.
If you don't end up staying at the Nautical and don't use their private launch ramp (glorified dirt ramp...but works well), def. take Matt's advise and launch at Cattail. The rangers are always nice and accomidating, the ramp is decent and there's usually ample parking. Def. worth the drive. The main marina launch ramp is owned by a bunch of nature nazi mother f*ckers that control the marina like they don't need the business. Windsor is the other ramp and it basically sucks. Shallow in spots and crowded...(hate to see you ding one of those herings, though it wouldn't be the first time someone did!).
While on the water, take a run to the south end of the lake (havasu springs) for a beer. Nice run. Don't forget to see Copper Canyon which is on the west side of the lake as the lake narrows while running south towards havasu springs. There's also steamboat cove (you'll need some help getting there, it's kind've hidden as you pass). And of course don't miss the sandbar! Good times up there. Hit it at the right time and you'll know why it's a cool hangout. You do have to beach in some seriously shallow water, or anchor on the inward side of the sand bar.
Either way, let everyone know when you're going. Maybe some of us can make it out there that weekend. And post some pics!
Here's the sand bar:
