Cruise

My s/o and I are going on a family cruise the ending of June. We owe $1,847 left as well as a drinking package which is $1,400 plus we need to pay for our flight, which we don’t know the price for that until it’s time to book the flight. The payment for the cruise ($1,400) is due April 1st. The drink package isn’t due and could be paid anytime but I would rather have that all together by April 1st as well. I get paid every week and my s/o gets paid every 2 weeks. I just need help on how much could be paid off every week and every other week from the two of us so it can be added all up by or before April 1st but we’re also trying to put money to the side to just have some money, for emergencies, and things we will need. I was thinking maybe $150 every week out of my paycheck and possibly $150 or $200 every other week from my s/o. I’m just trying to make sure we have all this paid off in time for our cruise. Other than the cruise, I’m also trying to come up with new remedies on how to save without spending.
