Bummer about Crowne Plaza, it's a nice one. Are the booked full?
One of the nicer hotels we have is
The Portofino Hotel. It can be pricey though, I'm not sure what your budget is.
Across from Crowne Plaza is the
Best Western - Sunrise. It is nice inside and near the pier and close to Hermosa, which is where a lot of the night life is.
Avoid at all costs the Ramada Inn on PCH and Ruby St., it is a dump.
Also someone recommended the Pier lodge which used to be nice, but has kind of fallen off lately. The last person I knew that stayed there said it had a musty, moldy stench throughout the whole place and they relocated to the Best Western. I would avoid that place as well.
There are quite a few nice restaurants in the Redondo Pier area that are in walking distance of the Portofino or Best Western. On the Pier check out
Kincaid's or
Old Tony's. In the Marina check out Blue Water Grill or The Chart House. Let me know if you want some bar names too, those are my favorite.
