I always thought you gave a shower gift and a wedding gift. I have always done so in the past. Even when I had to travel, let's face it, many weddings are still destination for the guests, even if it is still in the US. But, it would be kinda sticky to ask your non gift giving friends to give you more gifts. Maybe you can spread the word to the AHR guests, they really should be giving you gifts, at least they should cover the cost of their dinners.
