Holiday,what to do

That sounds like a really kind, but slightly ill thought out offer.
It's lovely that your son wants to do things with you.
Can you tell him how deeply you appreciate him and that you'd love to do something quieter another time, but you really think this is a young person's activity and you'd be much happier knowing they're having fun and can't wait to see the photos

Definitely say thanks but no thanks. My son and his wife invited me to go to the beach with them and their children today and I said no . The thought of those traffic jams in the heat.
We brought them up to be polite and they are!

That is nice of them to include you Kir you must be important to them.
I feel like others that I would decline this time. Driving around in the heat is not fun and if you are anxious it may spoil things for them. Maybe you could fly out and join them for a weekend at the end of their trip.

They are always wanting me to do things with them, lunch,go over to their new house etc. I think it's because they are not youngsters and want to be part of a family. It also annoys son that his brother never makes an effort even as mum and dad are getting older.

Kir
How very kind of them both. What a wonderful chance to make great memories with them. Grab it with hands otherwise anxiety etc could grip you in a vice. Get on great with your dil and all will be well. I envy you. Don't take the safe route. Dawn

Is she Spanish? Why would a newly married couple wish to drive round Spain with a nervous MIL......er no, I don't think so.

No no no!!
I assume your flying in and hiring?
Let's assume it's Malaga. For an experienced driver this can be confusing let alone someone who has never driven on the right.
The Spanish are not 'forgiving' drivers.
He's likely to say oh, but we have the Satnav, that can cause more confusion
If you go ahead be prepared for a hit on the insurance (him being a new driver)
Again, if you do go ahead video every part of the hire car.
There will be little 'dinks'. This video proves that the 'dings' were there before you took over the car.

Phoenix, I liked ‘poidoning’

Very nice of your son and. Daughterinlaw to ask you to join them on their trip. If you are an anxious person, its best to excuse yourself politely, your anxiety might ruin their holiday. They are newly married, let them enjoy their honeymoon, so to speak. You don't want to be a gooseberry, do you?
Sara, I wondered that too ?

What? Still doesn't look right........

Aargh! "poisoning"

Sorry,but can't see the connection between going on holiday with your son, and food poidoning, unless of course he was doing the cooking!

Still, I think that as midgey says, it should be "thanks, but no thanks" on this occasion .

Another vote for no! Not wishing to sound rude, but why would two newlyweds want mother along for the trip? Do they think you might pay?

You never know, perhaps they are crossing their fingers that you will say no!

Sounds a nightmare! But kind and thoughtful of them to invite you, I would definitely say thanks but no thanks.

I feel like an extra limb when I go with a couple , if they are newly married maybe he is asking you out of politeness . I can't think of anything worse than driving round a hot country with a couple , even if he is your son , just say no not this time !
