Come and visit me!!
Well, you could sort of. We live right by the coast and thats worth a visit if the weather is anywhere near decent. The beaches are good and sandy though bloody cold. Tynemouth/Whitley Bay/Cullercoats probably the best. Get some chips and sit in the sand........Sea Life Centre in Tynemouth has some nice fish etc but bit pricey and doesn't take long to get round (well not for my 2)
More for grown-ups is a flea market every Sunday at Tynemouth Station (nice Victorian station)
What else?
There is the Discovery Museum in Blandford Square - city centre. It has things on over Easter for little uns like egg painting and craft. Its free & there is lots of things for my 2 (3&18mnths) to do in the activity room, plus restaurant with not bad food.....
Also Life Museumn nr Central Station but might be for older kids.
Don't know how old yours are, but if you are shopping in Newcastle and the kids need a break there is a good soft play area in the Recreation Centre in Eldon Square called Space Base......gets rid of some boredom.
Wet n' Wild - usual pool stuff in Wallsend
Erm, will post if think of anymore.
Not sure about where you can stay. Depends what you want and how old your kids are. By the coast might be nice........
Have a great time anyway.
