Really, I think Rick over at HolyCoast has a much better idea. In fact, I think it's perfect! lol!!
Now that Disneyland allows weddings to take place in the park (with proper approval - they used to be banned altogether), Disney may have to start allowing some sort of memorial service for those dedicated Disneyphiles who just can't stand to be away too long. Maybe they can charge them the cost of an annual pass (without parking - the dearly departed won't need that).
