If you wait until you have reached the max party size (4/4) and then get married to a spouse who is currently roaming with a party. He/she will join your Clan (and Kingdom) with that party. So you will now have a party size of (5/4) and can increase your army size with an additional party costing 0 influence. You can disband the party as normal and then it will drop back down to (4/4) and will be unable to create a new party past the maximum. If you choose never to disband a party at this point you will always have a party size of (5/4) and is exploitable.
