just got back today, had a lovely time, thanks for the recommendations!

At The Deep you will get wheelcair users and carers in for discounted price.
In Hull there are loads of good free museums and art gallery.
East Park on Holderness road is really nice and has a nice play park and cafe
You could go to the races in Beverley
Honeysuckle Farm brill or try Cruckley Farm
Beverley has Tescos and Morrisons and Heron so loads of shopping there
Kingswood near Beveley has a cinema, bowling alley. McD's. KFC great pubs and a few nice restruants.
10 in Hornseaa is nice and Sullivans for Fish and Chips are the best

And please it is nor North Humberside anymore but back to East Yorkshire, apart from that have a good time

The Deep (Hull) is worth a visit.Very big submarium.Lovely bits for children,sn included.They usually do a couple of days a year specifically aimed at sn children where they turn off any flashing light bits and it is silent and they have BSL signers showing people around.Dunno when they are though,sadly.

dd loves it and we have an annual pass so visit quite often

The leisure centre at Beverley is only a couple of years old and has some lovely big changing cubicles.

second Bridlington - lovely, lovely prom, and a nice seaside town.

I worked in Hull as a 20something a couple of decades ago. Where I went out would definately not be suitable for a family holiday!!

I would recommend Honeysuckle Farm and Bridlington too. If you took at trip into Hull there the Deep which is more expensive but really great for a treat on a wet day (if you do go book tickets online so you dont have to queue. there also a country park at the Humber Bridge which has wheelchair accessible walks.

Bridlington is very flat and accessible. It's undergone much improvement along the sea front and is a really pleasant day out in nice weather. North side has the usual sea-side paraphernalia and the harbour. The southside has an excellent, clean promenade and vast, sweeping beach. The facilities are excellent there.

Beverley is accssible and pleasant enough for a short visit, but great for restaurants.

The most wonderful place in Hornsea is Honeysuckle Farm. It's not expensive, about a tenner for all of you, I think. It's a petting farm with cows, sheep, pigs, goats, etc, who are all very friendly and grateful for the little food pellets you purchase for 10p a bag. The cows are milked regularly and the milk is used for the lovely fresh ice-cream. It doesn't have lots of frills but it's just a lovely, stress-free day out.

I might add some more as I think of things. I really do hope you have a lovely time.

looks nice in pics is it wheelchair accessible do you know?
