I really struggle to see necessity in babies and toddlers travelling on a plane. Other Mums that I know who have taken their family on holiday, dump the kids in day care so they can go to the spa, enjoy the all inclusive free drinks, plus top up their tan. It sounds like most holiday clubs are 9-5, so in my mind im thinking why bother taking them when you've got your own child free agenda going on. Others swap tips on how to have kids and still enjoy the entertainment, so you get ground floor rooms so DC sleep & you get wasted during some resort event.
We chose out of courtesy for others not to fly with young children, as we know behaviour can be unpredictable, it just wouldn't be fair. Plus in 14 years we've discovered you can have a great time and great weather in the U.K., where the beaches are pretty much the same. DS isn't a fan of raging heat even in his teens, so we'd have a grumpy child on our hands more than likely.
We don't miss flying to exotic places, other locations like Paris aren't really set up for children, it's more of an adult thing, so pretty much rules that out. Like for us, the chance of something happening has ruled out London.
I know some parents book a holiday based of children's clubs. I've got no issue with them, but if your children are packed off every day 9-5, what's the point? I don't get why you'd pay so much to not be with your children.
Our best holiday was going to a posh restaurant at lunch, meeting other like minded families, who we spent the rest of the day with, swapping excursion ideas, nice beaches that I don't think you could find abroad. A few times we've booked the same time of year and our DH's & DS's have gone surfing together, whilst we did girly stuff, various workshops etc.
I honestly advocate various UK locations for a break, over abroad, I can honestly say I don't personally wish to go on a package holiday again. It's nice having a change of scenery & being able to do things I wouldn't usually get the chance to.
If you are going to fly as I mentioned previously, little bags 'from your child' with a few bits in, cheer fellow passengers up, they're less likely to be annoyed at any loudness, bad behaviour. Plus free ear plugs to cancel out noise. It seems like most feel it's their God given right to fly and wouldn't compensate others as it's apparently like catching a bus or train. Maybe get t-shirts made up saying 'Deal with it!'
