My parents were the same, always wanted to go somewhere but always had to spend money on other things. They left the UK for the first time this year because we (the 6 kids) pretty much forced them to. We all put together to get them passports and pay for a week in Majorca. They were unsure about it, questioned whether it was worth it, said it was a lot of money to spend on something that would be over after a week, but when they got back they wouldn't shut up about it they genuinely loved it, they were like excited children at Christmas. It felt like the roles were reversed seeing them like that, they were adorable
