Question about a goal before a purchase

I won't get into all the details of our finances, but tldr we are 40/40, 3 kids under 13, net worth $1.9 mill, guaranteed safe income of about $250k by 57, up to $340k by 65. All our big goals are basically funded...

*house paid off

*rental house paid off

*retirement more than on track

*6 month emergency fund

*no debt

​

The only goal left is I made a goal of having $30k in principle in a 529 for each of our 3 kids. Currently the oldest does, so we only have the younger 2 left to fully fund. Going at a normal pace, it should comfortably happen in 2 years. They are currently ages 10 and 5.

​

Anyway, that is my goal and I thought it would be cool if at the end of that goal to get annual disneyland park passes for all 5 of us. It would be $5k and we would probably go 5 times for 5 days each within 365 days. It is a lot I know, but it would also be equal to only 1 month of savings for us. The more expensive part will be the stay there each time plus food etc

​

I know this is a silly goal, but its something I feel I would like to do at least once while the kids are still young.

​

Anyway I am wondering if this is something you would hold off for 2 years on to complete the last of our financial goals as a reward, or just basically go ahead and do it in our situation.
