I'm fine with the change except that I don't think it will do all that much to avoid crowding. I mostly visit the Seattle lounge and I don't see that many kids in there maybe it is different elsewhere. I assume American Express is doing this the way they think will be best for their best customers and I think limiting access to a certain number of visits may affect those customers more than limiting families all entering on one card. I assume that is why they did it that way. If the families wanting entry are the high income people they want, then they shouldn't mind getting a card for each spouse. At least I assume that is what they are thinking. Personally I usually enter alone or with one guest and it is usually packed with other people who seem to be alone, so I don't expect much to change.
