GRAMMAR POINTS TO REMEMBER
1 DON’T HAVE TO (The Ultimate Luxury):
- Meaning: It is NOT necessary. You are totally free from this chore, obligation, or cost. In the context of a luxury resort, “don’t have to” acts as a huge selling point because the hotel does everything for you.
- Resort Context: You don’t have to clean. You don’t have to cook. You don’t have to pay extra. (You have the absolute freedom to just relax).
- Structure: Subject + don’t/doesn’t have to + Verb (bare infinitive).
2 MUSTN’T (The Strict Rule):
- Meaning: Do NOT do this. It is a strict hotel policy, a safety hazard, or illegal. Breaking this rule could result in fines, danger, or being asked to leave.
- Resort Context: You mustn’t swim at night. You mustn’t break glass by the pool. You mustn’t smoke in the room.
- Structure: Subject + mustn’t + Verb (bare infinitive). (Never use “to”).
The Advertising Trick: Hotels use “don’t have to” to make you feel like royalty (removing stress), and they use “mustn’t” to keep the property safe and orderly for everyone else.
