Think I got carried away with my plan

This is my 18 day dream honeymoon I have planned for the summer of 2027 so I have 2 years to save and if I don't have enough saved for it by then I'll push it back another year if I have to. Like I said I got carried away and the budget went out the window really quickly but I was enjoying it so I kept going do y'all think it's a bit excessive.
