Please note that THE Show is not only the St Tropez, which is right next door to the Alexis Park - but also the San Remo (which is kitty-corner from the MGM. Ther are fewer exhibitors, but some much larger scale rooms there.
IThese are indeed BTB shows, but if you are cognizant and respectful of this, most exhibitors will spend time with you, particularly when it is slow. After all, many of them are enthusiasts/hobbyists at heart.
