I'm thinking Ashlin Farm Barns in Lincolnshire where Stacey Solomon stayed, they are luxury holiday cottages but are huge. There are several of them, all near each other, so she could have easily rented a few. Emily Norris has also stayed their twice and Soph follows Emily too. I can just imagine her booking there as it's a safe bet, with friends having stayed there, plus it's not massively far away. She's not following the account, so just a random guess.
Also, what's the point decorating the van like that, everything is going to go flying, it's actually dangerous! Also dangerous the fact she has an elf partially on the hob.
