Plan a Holiday Travel Budget for Thanksgiving and December Trips From Your Real Fares and Dates

You are a practical travel budget planner who helps people see the real cost of holiday trips before they book. Thanksgiving and December are the busiest and most expensive travel weeks of the year, and I want a clear budget for my trips built only from fares, dates, and costs I actually found. Use only the numbers I give you. Do not invent fares, fees, hotel rates, gas prices, or predictions about whether prices will rise or fall. If a cost is missing, mark it [NEEDS INPUT] and tell me where to look it up.

Trips I am planning, with destinations, travel dates, and how flexible each date is: [TRIPS]
Who is traveling (adults, children, pets) and any needs such as car seats or extra bags: [TRAVELERS]
Options I have found so far with their real prices (flights, trains, buses, driving distance and my car's fuel use): [OPTIONS]
Where we will stay and what it costs, or whether we stay with family: [LODGING]
Other costs I expect (parking, airport transfers, pet sitting, gifts to bring, meals on the road): [EXTRAS]
Total amount I can spend on holiday travel this year: [BUDGET]

Requirements:
1. Build a cost table for each trip with every line item from [OPTIONS], [LODGING], and [EXTRAS], and show the total per trip and per person.
2. Add the costs people often forget, such as checked bag fees, seat selection, parking, tolls, and rides to and from the station or airport, and mark any I have not priced yet as [NEEDS INPUT].
3. For driving, show the fuel math using my distance and my car's fuel use, and ask me for the current local fuel price instead of guessing it.
4. Compare the total of all trips against [BUDGET] and show the gap or the room left.
5. If I am over budget, list concrete trade offs ranked by how much they would save using my own numbers, such as shifting a date I marked as flexible, driving instead of flying, or shortening a stay.
6. Give a booking checklist with what to confirm before paying, such as the change and cancellation rules and what the fare includes.
7. Build a simple tracker I can update as I book, with planned cost, actual cost, and the difference.

Deliverables:
1. Cost table for each trip
2. Forgotten costs checklist
3. Budget comparison and ranked trade offs
4. Booking checklist
5. Booking tracker
