AITA Wife wants to travel without luggage for valentines, I do not.

We are a married couple (30M and 30F). We are planning a trip for Valentines to Europe from London where we stay. My wife chose Vienna and found a flight with Ryanair priced at 60 pounds return each. She suggested we should take that flight for a 4 day trip. The flight doesn’t include any luggage, with cabin luggage the flight is worth 120 each and she said we can manage without the luggage.

She said she wants to experience travelling for a cheap amount and doesn’t want to spend too much. For context, we are high earners and live way below our means so this is not due to a budget constraint.

I suggested that we should at least be able to take some cabin baggage as I don’t like travelling without clothes especially for a 4 day trip. We got into an argument and now she wouldn’t talk to me. I told her I wouldn’t want to go for a trip if this is how we would be travelling. Am I the asshole?
