My husband made a joke when he stayed in a hotel.

In this case, you may feel uncomfortable and embarrassed, but your feelings are reasonable. Here are some ideas you can consider:

1. Respect his decision: Although he doesn't agree to spend money to stay in a hotel, please respect his decision. He may have different views on money, or have other reasonable reasons not to let you spend money on a hotel.

2. Importance of communication: This may happen if communication is not good in advance. You can discuss with him before you leave and express your desire to stay in a hotel. Through communication, we can better understand each other's ideas and needs.

3. Dormitory conditions: If possible, you can learn about the specific conditions of the dormitory, such as hygiene and safety. If the dormitory conditions are not good, it may bring inconvenience and discomfort to your trip.

4. Other accommodation options: If the dormitory conditions are not ideal or satisfactory, you can consider other accommodation options. Finding an economical hotel or hotel near a business trip may be more convenient and comfortable than living in a dormitory.

5. Personal space and time: Even if you don't want to spend money on a hotel, you can still enjoy some personal space and time during your business trip. Try to walk around, taste local food or do other recreational activities to enrich your trip.

Most importantly, try to understand and respect each other's decisions. If you communicate with each other well, you can better understand his thoughts and needs and find a solution suitable for both parties.
