re Lonely Planet. I think their stamp of approval is the death knell for anything that they recommend. I like the Footprint guides.
There is web site called trip advisor. It can be a bit annoying to navigate but it has never let me down when it comes to hotels. It has classifications like family hotel etc and if you just search fr a family hotel and pick the highest ranked one in your budget you should be fine.
Since I started using it we haven't stayed in a hotel we weren't happy with.
It works on visitor ratings so it averages out pretty accuratly.
