Pfft, all I'm hearing are excuses.
Pack a lunchbox. Drive 5hr overnight and nap in the car once you get to the venue. Get a friend or carer for your wife if she can't be independent for a day or so.
If you want something bad enough, you do it. All I'm hearing is 'I can't go to a Regionals because I can't do it in comfort!'
You don't need a plane ride, a hotel, or a fancy restaurant.
Also, temper your expectations. If you don't play in tournaments often, don't expect to do well in your first tournament.
