Flights or trains for each version
Use a realistic range for the dates you might actually travel, not the cheapest day of the year.
A couple’s travel budget is useful before anything is booked, not just after you’ve started spending.

Before either person books anything, estimate what the different versions of the trip actually cost. That is more useful than agreeing to split the hotel later.
Couples get stuck because they are comparing two trips that only exist in conversation. One person is picturing Lisbon for four nights. The other is picturing Mallorca for six. Both sound possible. They are not the same budget, the same dates, or the same kind of days.
The job is to put those versions next to each other with rough numbers attached: flights, stay, local transport, a few planned activities, and a note on what you expect to share versus spend individually. Then you can choose the trip, instead of discovering the cost after the excitement has already settled.
These are working estimates for two people, not a quote. The point is the shape of each version, not a perfect spreadsheet.
Mallorca for six nights can look similar on flights and then jump on stay, transport, and the extra days of food. Lisbon for four nights can look cheaper until you put both of you in a central stay during a busy weekend.
Once the versions are visible, the conversation changes. You might shorten Mallorca, move Lisbon to a quieter neighbourhood, or drop a paid activity so the stay you actually want still fits. That is budgeting as part of choosing, which sits inside how to plan a trip as a couple.

Use a realistic range for the dates you might actually travel, not the cheapest day of the year.
Save two or three stays per destination with a nightly range. Location often matters more than the last fifty euros.
Airport transfers, a rental car, metro cards, parking. These are easy to forget and they change by destination.
Tickets, a boat, a special dinner. You do not need every cafe. You need the things that would change the total.
Stay and transport are usually shared. Some meals, shops, and extras are not. Naming that early avoids surprise later.
Awaii keeps the ideas and the planned costs next to each other while the trip is still changeable. You can save two destination versions, attach stay options with rough prices, and see whether the trip you are imagining still fits. If it does not, you change the version — shorter dates, a different area, fewer paid extras — without rebuilding the plan from chat.
That is the point of a travel planning app for couples: not a ledger after the fact, but a working picture while you still have a choice.
Yes, at least roughly. Two destinations are often two different trips. Estimating both versions before booking tells you whether the longer stay or the shorter city break actually fits.
Ranges are enough. You need a working picture of flights, stay, transport, and a few planned activities so you can compare versions. Exact receipts come after you choose.
Save both versions, attach rough costs, and choose with the picture in view.
