Typhoon Lagoon Rental Umbrellas

We are a party of 5 so we will need to reserve two umbrella/chairs set ups since they only hold give 4 people bracelets per reservation... Do anyone know if we book 2 umbrellas (Disney site does not allow to book 2 at once so we will have to book in 2 transactions) if we will have two umbrella set ups together or do they not guarantee that? Concerned that we could have one umbrella on one side of the park and the other far away.
