We are planning our first trip to Disneyland this May. We are WDW veterans so I'm having a hard time estimating how many park days we will need at Disneyland. We are staying at the GC for 4 nights and are definitely planning on 3 park days. We are questioning whether we might need a 4th park day. We will have our 2.5 year old and 7 year old with us...any thoughts/opinions on how many park days we should plan? At WDW you can add a day to your existing ticket and pay the difference. Does it work that way at DL too? If on the 3rd day we know we want to come back, can we add a day to our tickets? We will be getting hoppers for sure and planning to get the maxpass. TIA!
