Opinion on Cabin Choice...CP

Caribbean Princess... What would you choose? BA on Lido(looks like smaller balcony than BB's), BB on Caribe (larger balcony), or BB on Riviera - accessible cabin (larger cabin & balcony..but I don't know if the balcony is larger than Caribe). All roughly same price...

OR...another choice would be a BA guarantee, and hope for a mini-suite...
