We have used both. I would use Wegoshop again in a heart beat. We did have troubles with gardengrocer - nothing terrible but they could have been more communicative. For instance when we corresponded with them by email we never got a response letting us know that they received it. We got our order and everything worked out ok but it just could have been better kwim? Wegoshop was a whole different story. On the day we arrived, our shopper (I can't remember her name off hand) called us because she wanted to clarify some of our order and there were a couple of specific items that she couldn't find so she wanted to make sure what she got us would be ok. She arrived at our room at the scheduled time and even told us that during our stay if we needed anything else it was included in the original delivery fee which I thought was nice. We were really happy with Wegoshop!
Someone asked what kinds of food do we order? We ordered sandwich bread for making toast, butter, Milk, cold breakfast cereal, some snack foods like Cheetos, beer, wine, pop, and bottled water. We tend to eat breakfast in our room and had lunch and dinner in the parks, DTD, or resort restaurants using the dining plan.
hth!
