I attended a conference at the Long Beach Convention Center. Travelling with 2 adults and 2 kids, I didn't want to cram into a hotel room and eat out all week - wanted something with more than one bedroom and at least a rudimentary kitchen. What a find this was! Closer to the Convention Center than any hotel but the Hyatt, scenic, private, and with just the amenities we needed, "The Boat" became the favorite place for all our friends at the conference to come and relax. (Lost track of how many trips to Albertsons we made for more cheese & crackers, to feed the hungry visitors!) The kids (6 & 9) were in heaven - little one spent hours with a hand towel "swabbing the decks!" - and 3 months later, they're *still* telling everybody about "our" boat! I'm still patting myself on the back for finding this place :-)
A few downsides one should know about:
1) Noise! Party boats, early morning bullhorns, schmaltzy music all night that we could only assume was coming from the Queen Mary's ballroom, and tour boats going by all day, pointing you & the B&B out to the tourists. Didn't bother us all that much, but I can see how it could.
2) Somewhat rustic water-saving bathroom - we enjoyed the novelty, but some might not.
3) We found the breakfast baskets a bit unremarkable, and a little sparse for the 4 of us. Management is reasonably responsive to requests, though, and you can always stock the fridge.
4) Parking is a pain. We lucked out and had a friend in the Hyatt without a car, so she checked ours in there for us, right across the street. The recommended parking at the Aquarium is neither close nor cheap, and the Hyatt parking costs even more if you can't get guest rates. And unfortunately, you need your car to get to any source of groceries. (You could walk to Albertsons on a very energetic day, but you wouldn't want to carry much back!)
Overall, though, the downsides were well worth it - if I ever get back to Long Beach, I wouldn't stay anywhere else.
