I leave bright and early Wednesday for Cancun and GP with my 3 girlfriends. I see where previous patrons have recommended taking Bubba insulated mugs. I looked at walmart today and I couldn't find a little Bubba. I found a 32 ounce and a 54 ounce. Even the 32 ounce seemed big. Is that the one everyone is talking about or is there one even smaller and I just haven't found it? Thanks. We're all SO excited to get there!
