Dizmo, I still think you would be better in your own home especially as you mentioned diarrhoea.You don't want to stuff yourself with a lot of rich food. Years ago when two of my grandsons were young I used to give them each a Christmas card. Inside I would write----'This is to give ??? the choice of one of the following (various items such as a new jacket, trainers, games, toy etc)Then after Christmas we would have a day out to get whatever each had chosen. The memory still lives on many years later .They loved it.
Or you could always put some money inside a card and then ask them round and give it to them. Kids love money!!!. But above all think about yourself ,your health is paramount.
