Welcome Party

Hello,


My wedding is the weekend on February 18-20. In Key Largo, FL. I am doing my welcome party the 18th, wedding on the 19th, and a farewell/friends and family day on the 20th. My venue is a owned by a company who rents out houses that are on a big piece of land, which we have for the whole weekend, and they rent these properties out specifically for weddings. The property has its own beach, pool, houses, etc. Everything is basically a la carte with this venue. The venue has the vendors that they work with, but I have the option to book outside vendors as long as they have general liability insurance.
Vendors these days are expensive, especially catering companies. So I’m struggling with what to provide as food for the welcome party and for the friends/family day. I really don’t want to hire a catering company for my welcome party/farewell party, being that they’re pricey and it’s hard to get a small catering company who has general liability insurance. So basically what I’m asking for is help deciding on what to provide for food. I’m looking to have my welcome party and friends/family day be a little more relaxed. For Friday, provide beer, wine, & seltzers. For Sunday, probably have all the guys BBQ, serve beer, light drinks, seltzer, etc. For the welcome party, I would go with pizza for all I care! Lol. Is this acceptable for a welcome party? Need help! Lol
