Hi Georgia,
Forget the boring drive down to Gib etc till the weather gets nice and sunny plus the daylight hours are longer. There are plenty of places to visit "up north" and only take a fraction of the time to get there. May not get the greatness of Frampton or Gib but you won't be tired out from all the driving
Although I've not been anywhere since October that shouldn't matter.
Worlaby and Bonby Carrs, MSQ, Alkboro Flatts, Barrow Haven, North Killingholme Haven, Black Bank, Laughton Forest, Scotton LWT Reserve, Epworth Turbary, Crowle Moor, viewing Reeds Island in fact anywhere around north Lincs is good on it's day.
If you want to go a little further but but still in north try the Fitties, Tetney, Cleggy, Bardney Wood etc
Try and get a copy of GPC's Where to Watch birds in the East Midlands published 1996 ISBN 0-7136-4460-5 I found it to be a valuable addition to my birdwatching and it still is an excellent reference work to anyone who wants info on that area.
That are loads of members who have local knowledge and I'm sure will only be too pleased to give you info required.
Another good spot to watch and has (or at least had the last time I visited) the addition of a snack bar on site and that is over the Humber Bridge to North Cave Wetlands. Not forgetting Blacktoft Sands.
Good luck!!!!!!!!!!!!!!
Kind regards
Max
