Festival themed hen do

[cleareyesfullheartss]

Looks like the place I have booked for my sisters hen do isn't going to happen (weekend before restrictions lift) but we are allowed 30 outdoors, so I'm thinking of throwing a festival themed garden party.
Any good ideas of what we can do? Garden is large, have patio area that will become dance floor with lights and possibly kareoke. But any other ideas to make it special? I have a pop up bar we will use, and will buy all food and drink for everyone (approx 25 ppl)

What about about a food van, I don't know if you are gun drinkers but maybe a little table with different fruits to in it in nice dishes if fizz is your tipple different things to go in that. Goody bags, they don't have to cost a lot.

Warmth - do you have a heater or a firepit in case it's chilly? I've been to outdoor weddings where there were baskets of fleece blankets that were personalised like X&Y's wedding which was nice when it got a bit cold.
