It's reading threads like this that make me grateful my family is normal ish 
I have been to various cousins weddings the past 4 years - all different with different invite stipulations.
1 - wedding was close family only. Aunts etc and few of us cousins. Great reception at relative of grooms house with huge garden/fields. Marquee, things for kids to do including magician, sit down meal ice cream van, hog roast dance floor. Bring a bottle and some drinks provided at an erected bar. I don't drink and bought myself non alcoholic wine for meal, soft drinks all provided and far cheaper than a bar. Best wedding reception I have ever been too. 
2- church wedding and then hotel reception about 8 miles away. Nice garden and dance floor with bar. Sir down meal with wine/water with a later buffet.
3- was 100 miles away. during term time and I didn't attend as too far for a day and no funds to accomadate DS and I. Cousin fine and understanding.
4- church wedding with reception 10 miles away. Again nice place with outside space for children to roam, dance floor and bar. Sit down meal with wine/water and later buffet provided.
5- last week. An hour away at a beautiful manor house/ hotel. Registry service in hotel, huge outside space with indoor bar, magician for children, meal, plenty of pims, OJ, wine and water for guests, dance floor and bar and also a BBQ.
