I went to disney with my 5 month old several years back but have also been to Aruba several times. I shipped the formula before I went and had it waiting at the hotel when I got there. Sun block is going to be an issue as well. My physician and pharmacist informed me under the age of 6 months can't use sunblock. Keep very cool cover ups to cover up with, hats, etc. I have stayed at Hyatt-they're great about everything. There is a store close by-next hotel over-Playa Linda-small store reasonable prices where you can buy necessities but I'd bring enough diapers/wipes where they are much cheaper from home. Bring your own folding cooler from home, fill it with ice from hotel to keep formula cool, etc. If you bring a stroller, make sure it has an umbrella attached. Anything else, I'll try to help. Hyatt is beautiful, great restaurants, great people.
