*nods* With how much the flight costs, you feel like you have to make the visit worth the time and money. Every trip I've ever taken out of state to see someone I had a relationship with has been at least 4 days, and up to 9, I think. When my partner visits me and my husband he stays with us for 10 days. I'll try to get hubby over to this thread after work today in case he has any insightful comments or advice, having been in a similar position to you!
