I go to my parent's home in florida every year
Why do you enjoy going so much?
I need to go to my parent's house as many as I can. If I don't, they'll never talk with me again.
I think that at this point it is safe to say that this is tradition now. You should definitely do your best to keep up with it now because it makes them so happy.
I just hate the fact I feel forced to at times though. It is a great location however with lots of sun and fun.
Family get togethers should be fun and not forced. If they ever stop talking to you because you miss a trip there then it is their problem and not yours. You have tried your best to go there most years.
