Holiday surprise is ruined

Me (22f) and my bf (22m) are together for over a year now. This june we went on a holiday and it was amazing and I planned to go again this summer and he doesn’t know. I really love him dor who he is and I just want to make him but my dad said it will hurt him because I will pay the trip and my dad said he would feel defeated and not manly. So my dad and I had an argument and I was trying a whole year to earn money for this holiday and now my heart broke. I worked as a piano teacher and saved all my money. Also I dont want to hurt my bf but we could have a lot of fun. I love him a lot what can I do?
