DW is still bitter that her sister didn't travel from Connecticut to Florida for our wedding 3 years ago. She understood that her dad, at 87, couldn't make it, and her 20 year old daughter was basically pissed at her for leaving the country (they've since made that up)....but when my sister and brother in law, and my best friend and his partner flew from the UK to Florida for the wedding, DW was rather annoyed that none of her family and friends made it!
We stayed with her sister for a week after our wedding, DW stayed for 2 whilst waiting for visa, and we visited them last year. Then this Easter they were looking at coming over to visit but don't seem too keen even when DW was offering to contribute to the airfare! Oh well, if they don't want to visit the UK.....
