I would say not a chance it is worth it If you have to wait 6months to pay it off. You just said you got hit with unexpected bills which have already made the food budget push you into debt. Clearly this is not a good time to splurge on a trip in the first place. However if you are choosing to splurge on the trip anyway then it is critical not to dig an even deeper hole. What if new “unexpected” bills occur? Illnesses, injuries, broken items to be repaired at home, war raising gas and food etc, or all of them and more hitting you in the next six months. If you don’t go to CRT and other extravagant meals then the worst you can say is “we had a great trip at Disney world” on the flip side if you are careless on this trip you could end up with mountains of debt that crush you for the next 5 years, piling up and have long term significant consequences to everyone in your family-possibly piling up so that you need to work longer hours etc and the kids have less family time as a result. There is no comparison between the risks vs benefits here. None at all.
My advice is to focus on eating cheap, bring snacks and choose sit downs where you can split. If people aren’t real hungry when you sit, there are a lot of great restaurant experiences without prefixe prices you can focus on, share and enjoy it on the ultra cheap. Ideally stay somewhere you can cook in the room offsiteas much as possible but regardless the goal should obviously be to budget tightly not bury your family for a marginally improved experience. The trip itself is the splurge, approaching it with the mindset to go all out since “we are on vacation,” when already in a hole is extremely dangerous imo.
A final push: keep this in perspective. You will walk up a windy staircase, sit at a table, some ladies in make believe outfits will walk by and wave at you and you will eat mediocre food and get a plastic wand while looking out a distant window at the same views you had before you got to your table.
Then make a list of all the things you don’t need to pay significantly more for-parades, splitting desert at an occasional nice restaurant, seeing ladies in make believe outfits waving at you, rides, shows, etc etc. the core of the trip will be unaffected if you are careful with your budget, putting your families financial stability in jeopardy for those marginal improvements is pure insanity.
