You will need to be more specific about what activities you like and what you can afford in USDs (not descriptions such as "mid-price) for the hotel. Exact dates might be helpful, number of people also. I would assume 1 since you use I but a lot of people say I I I when it's we we we.

If it's one week I'd just stay on Maui. If you have two weeks then you can add a second island if you want to.

I stayed in Lahaina, because I like having a town to walk around in and Lahaina's a lot of fun. We stayed at Lahaina Shores a condo hotel (but it's not a resort and doesn't have much of a beach so may or may not be anything you're interested in).

The highlights for me were Haleakala (the volcanic crater, it's amazing), the Old Lahaina Luau, walking around Lahaina (there's a self guided walking tour you can do there), a show called U'lalena at Myth & Magic Theater.

Hawaii is trickier to plan than some vacation destinations, I think, because of the different islands. If you haven't yet, do get a couple guidebooks from the library so you can read & see photos about all that is possible there.

If you have two weeks I'd do one in Maui then the other in Oahu.

Big Island, Maui are fairly similar. I'd either visit Oahu or Kauai for a second island.

First, you should re-tag your thread "Hawaii".

If you have 2 weeks, you should definitely go to another island. If you peruse other threads on Hawaii, you will find that there are enthusiasts for each of the 4 major islands. Although I have spent most of my visits on Maui (relatives lived there), I recommend Oahu for your second island. It really is "Hawaii Central". I've only been there once, but looking back on it, I'm so glad that I visited there, particularly since I will probably never get back to the islands.

Another activity to add for Maui is Warren & Annabelle's Magic show. It is a pile of laughs and some really great magic. Try to go when Warren is the magician.
We also enjoy snorkeling and just driving around. What can be better than getting a take-out lunch and sitting by the ocean watching people and whales?
A day trip to the upcountry is worth it. We've been up to Haleakala a few times (twice at night and once during the day). It's a toss up for the sunrise because of fog, but the daytime trip is interesting.
Just remember to have a great time and take time to relax. It's all about Maui.
