Holidays of note for us
We did a great road trip with in America plus portions are big there but was a few years ago and for a month.
Safari in Kenya plus beach, week for each and really very nice hotels.
Cruise, they can eat as much as they want and then day trips from the boat. We did a Med cruise, Rome, Pisa, Cartegena, Gibraltar, Monaco and some other places. I was surprised how much we all liked it. I liked how we just did nothing but read, relax, have dinner, swim and gym for a day or two and then had a day trip.
Hiring a Motorhome, pub dinners, hiking, swimming in the sea and travelling about.
Canal boat hire, they would be allowed to steer the boat, did a week, we had great weather. Board games, wildlife spotting and visited a couple of museums when we tied up in Stratford upon Avon.
Road trip through France visiting D day sights, eating out, museums and the beach.
