I'm building quite a complex travel company site, where things like different vacation packages need to be linked to different modes of transport, hotels, various different statuses and categories etc.
For example, a tour might have 4 different trains and a boat. I have created a channel, Trains, and another channel, Boats. I'm wondering what the best way to link these up is.
What are the advantages/disadvantages of using EE 2.6's improved Relationships feature vs something more comprehensive like Playa?
