I got most of my information from a shop that is considering making the switch for the reason I cited. I assume they have thought it out, but it is hard for me to understand how switching your agency will improve the situation. If PADI travel is creating competition for dive travel, then that competition will exist regardless of your shop's affiliation. As someone from that shop said, their customer base for travel likes the personal touch they provide, and he does not think they will lose many of those customers.
