So my family of four were given 2 day tickets with park hoppers after some issues with our last trip. We are thinking of taking a short trip in April. DH is attending a conference and will only do a couple days of parks. Girls and I will spend 1 or 2 more days in parks that I need to purchase. I'll just purchase base tickets without hoppers. If I purchase these before hand and they are all linked to MDE can I specify which ticket to use at the gate, ie park hopper or base? Would it be easier to just purchase tickets at the gate for the days we don't park hop and not link those tickets?
