I've been building up Mt Holbston, and I was at a loss of what to do on the largest lot overlooking the ocean in the beginning. So I decided on a sort of makeshift boardwalk. It's where the Restaurant, day spa, grocery, bookshop and the consignment stores are located. Here's a couple of pics - ( excuse my debug lights :D )

There's no festival lot in the world, because I got tired of having parks "close" when the festival ends and sims can't even use the toilets, so I don't often use them anymore. This way they can still go and do stuff on the boardwalk.
